Lastly is crucial evaluation and bottom line. I am necessary to provide some examination of the journal that has been referred. In addition, logical feedback and own view on the journal referred possessed provided.

Introduction and basic idea of RFID

RFID (Radio Consistency Identification) is a wellknown programmed recognition system in this 21st hundred years world. It uses radio waves to retrieve the info stored in a tiny circuitry. (English Expression Information, 2010). The very small circuitry is thought as chip or label. Chip technology allow us to transmit information to these devices and also obtain data from it by using radio waves.

RFID was created to enable readers to capture and transfer data to a pc system without requiring a person to be involved. (English Word Information, 2010). An RFID reader just need to send radio regularity alerts out to the tags and reads the impulses that come back again from the tags by means of a unique serial number. The RFID device acts the same goal as a bar code that provide a unique identifier for the thing, but it was a scanning technology alternatively than using radio signal.

Below is the summarize pub chart that show impact of RFID on business performance. It show the impact or result of an organization that take up RFID system contrast with non-RFID system. Pub chart below is the summarizing according from the desk of statistic which manage (Google Image, 2010). Refer to Appendix (Part A) to the table of statistic.

2. 0 How does an RFID system work and its own performance

RFID belongs to a group of systems refered to Auto Recognition System. This methods automatically identify objects, collect data and enter in those data directly into computer systems with no human intervention. Here are the quick main flow of the way the RFID work if warehouse make use of it for inventory control. (Ray Low, n. d) :-

Tag gets into RF Field

RF Signal capabilities Tag

Tag transmits Identification (plus Data)

Reader captures Data

Reader transmits Data to Computer System

System determines Following Actions and go back tag data

Reader may transfer Data to Tag

Figure 2: The primary movement of RFID

At simple level, RFID system consist of 4 main element in order to work such as tag, reader, variety system and software.

The tag which made up of a microchip with an antenna will trasmit data to the RFID reader when receive information. The audience transmits out electromagnectic waves and then converts the air waves to a far more usable form of data. The tag receive the signal utilizing the antennas and respond by trasmitting their stored data. The microchip and the reader do not need to be in each other's line of vision to work properly, and the transmitting or reading process is ultra-rapid. (Intermec, 2007)

All of the info and information accumulated from the tags via its antenna is then transferred or decode by using a communication software to a host computer system, where in fact the data being stored in a secure database through a cable connection or wireless connection. The info is captured and passed to computer system for interpretation, safe-keeping and action. (Intermec, 2007). The procedure or flow will then continue again and again when want to identify another subject. The RFID performance increase by applied the right circulation of RFID process.

In order to raise the reading section of RFID, it can affix more antenna and increase variety of reader in RFID. (Ray Low, n. d). The greater antenna included, the reading area is bigger. Because of the seamlessly flow and bigger reading area of RFID system, it resulting in optimised time management for product delivery process or for inventory management. By applying RFID, it can promote operational efficientcy and perfection.

Advantages of RFID

RFID system has many advantages over standard solutions as it converts the procedure become automatic. Typical monitoring system requires manual connections, which include labor intense, very frustrating and error prone. With RFID solution, it definitely has significant advantages that can raise the efficiency of inventory and management. Here are some of the benefits of using RFID in inventory management:-

3. 1 Efficient Inventory Tracker (Intermec, 2010)

The main benefit to using RFID in the warehouse is to boost inventory traffic monitoring, especially where the technology is not needed line-of-sight to learn RFID tags, in the same time, inventory can be performed in a highly successful way.

RFID using the real time, high accurate technique to keep track of raw materials, work in process product and completed products. All inventory levels and safety stock in the warehouse can be record within a second. With RFID solution, inventory can be up to date instantly without scanning, product motion or human participation. The fully automatic system also allows inventory status to be established and generate documents automatically. Besides, it also alerts the retail store once the previous little bit of product is bought and avoiding out-of-stock occurrences.

In addition, visitors covering the cabinets and other warehouse storage location can automatically recognized the removal products or items and upgrade the inventory details. If the item misplaced, the RFID audience can automatically search the item by reading the specific product ID amount and staff have to place it back. It does increase the inventory efficiency in every the while.

In true to life, Sonoco is one of the manufacturer of paper industry which adopt RFID to handle their inventory. In the event the paper process is choose or used RFID technology, it'll eliminate those risks and will take full advantage of the tags stability by integrate the tags into the paper cores while making process. By shifted through the supply chain that using RFID technology, the tags would become more secured and not easy to ruin. In addition, it will help the firm to diminish the amount of waste and spend less, it will also reduce the variety of lost delivery that made. Make reference to Appendix Part B(I) for futher information on the research study.

3. 2 Advanced Form Rate (Searching) (Shien-Chiang Yu, 2006)

In a warehouse, activity of sorting product is always important but it is frustrating and put through errors. Together with the using of RFID system, it makes the sorting activity become more easy and simple.

For example, the activity of issuing items from a store, staffs have to find out if the item can be obtained or not by bodily walking to the warehouse to check. By using RFID system, it eases the sorting and picking procedure because it captures real-time data, and provides accurate information about product supply in computer databases without physical activity. When warehouse staff need those certain items, the info that trace by RFID readers can help them eliminating the changing times for manual queries. Hence, it is very helpful in pick and form rate for increase the performance of warehouse management.

3. 3 Toughness (eHow, 2010)

In the environment of warehouse, it opportunity will have many dust and dirty thing on the products and the encompassing of warehouse. RFID tags are far better in working in harsh environment while bar code product labels have the condition on it. The durability of RFID tags that placed in the merchandise perform well in a variety of demanding environments. An RFID tag is securely located within an subject or embedded in plastic. It will eliminating lots of the problems where they are exposed to dirt and grime, chemicals or temperature. RFID tags have a tendency to be secured with the plastic which a lot more thoroughly and permitting them to be read within the harshest of environment like warehouse. Therefore, RFID definitely could work under harsh environment and RFID tags may be put in place extreme environment and perform to standards.

3. 4 Advantage management (Intermec, 2010)

RFID tags are essential place in to the product, items and preset assets. Inside the asset management, i will briefly identify the shipping and delivery and receiving of product between sender and device.

Shipping & Receiving

Identification of items will happen automatically with the exist of RFID taags and audience, the precise amount and type of product is immediately recognized to all parties. Quite simply, by coordinating the delivery information in a repository, warehouse employee can automatically build a record of what information specific in a transport containers that will send to device. The information can be used to improve recoveries and returns by users about lost and broken. Any lost or harm of the merchandise between your amount bought and received can be automatically identified for both shipper and device. (Puneet Mehrotra, 2006)

The implementation seem to be to progress well when the company use the RFID to their operations. In real life software, one of the company designed to use RFID is HP group. The using of RFID has transformed HP's shipping processes in an extremely effective way. Warehouse shipping and delivery tracking application helped in identify work in process or completed goods inventory. All of the products with RFID tags can be read as they are automatically registered in the shipment system. Warehouse worker can also know the item inside the cartons without available the carts. In addition, shipment list information that encoded in RFID tags can be read by getting firm and make the procedure become simplify and satify customer's necessity. Warehouse people can use RFID audience to simply scan the tags that devote the product to determine whether or not the products are complements using what was ordered. This wills totally reducing the amount of errors that may occur in delivery and acquiring. Besides that, all those error or faults can be diagnosed before the products appear or even after leaves the warehouse. Make reference to Appendix Part B(II) for futher information on the case study.

Disadvantages of RFID

Not all the applications of the technology and products are perfect atlanta divorce attorneys way, especially RFID which utilizes radio frequencies to transmit signals. RFID will face many issues such as costs, gain access to rate, security and RFID collision. Here are the discussions of each issue:-

4. 1 High Cost (eHow, 2010)

Cost is one of the major factors influencing RFID as it will be greatly expensive to put into action RFID completely. The RFID system is costly in comparison to other automatic recognition systems and it is a lot more expensive to set up compared with club code.

According to article from (Goal, 2010), it explained that the expense of one tag generally cost $0. 85. The costs is based on the volume, the quantity of storage area on the label. Some of the tags required to be designed for a given application may be expensive when made for use under extreme environmental conditions. The presentation of the tag which encased in vinyl or inserted in a label will also identified the price of the tags. Besides, almost all of the reader in RFID will cost from $500 to $2000, which be based upon the feature in the devices. The costs of antenna are about $250 and up. The fully useful RFID system cost is hard to figure out due to the different peripheral equipment and application software used. Besides that, following the assembly fees of RFID system, types of software used, companies may also need to hire a system integrator and upgrade network within facilities. Hence, it does increase the overall cost of an RFID system.

The estimation project charges for a medium company include (AIM, 2010):-

$90, 000. 00

Total

$149, 480. 20

Table 1: Estimation of any project cost

4. 2 Security Concern (eHow, 2010)

Methods of breaking smart greeting card also connect with RFID tags. Since the RFID system is not limited by line-of sight technology like club coding, another security issues could been develop. The security issue is the exterior or malicious may use high-intensity directional antenna to scan very sensitive tags. When RFID is utilized for high-security operations, frauds issues always is a possibility.

For example, a development competitor could build a high directional antenna to check out the tags in pickup trucks that heading to a warehouse. From the info being scanned, the rival may determine the flow rates of varied products or what's the material used in a particular product.

4. 3 RFID Collision (eHow, 2010)

Collision occurs when the alerts from two or more readers overlap, or even more than one label read at the same time, the tag struggles to react to simultaneous queries. So, it can be some tags will never be read or some tags are been read double, subsequently it will confuse the reader. Next, the RFID reader will fails to differentiate between incoming data because the read time is extremely fast.

This problem does not occur in bar code technology, as when club code is scanned, it is instantly verified from the scanner. To avoid label collisions, integrators use time section multiple access, which will make the readers programmed to read at differing times, alternatively than both striving to read together. Basically, the reader are instructed to learn at different times, rather than both seeking to read at exactly the same time. This ensures they don't really interfere with each other. Besides, many systems are use Anti-collision process to solve this problem. Anti-collision protocol enables the tags to consider changes in transmitting to a reader.

Hardware and Software Requirements for RFID

There are 4 main hardware aspect and software that are being used to implement RFID. You can find RFID tags, audience, web host computer and printing device. Whereas software that it needed is middleware. Below are the main the different parts of RFID (Intermec, 2010):-

Figure 3: RFID Component

5. 1RFID tags

Tags are very important in a RFID environment because they store the information that describes the thing being monitored. The more detail object information is stored in the memory of tags and is also accessed through the radio indication of RFID visitors. Most tags are just activated when they are within the interrogation zone. Chip tags contain recollection which can store or keep record. It has different sorts of tags (Ray Low, n. d):-

Smart Label, Cards, Belt

Unique Serial ID

Memory Space

Active and unaggressive tag

Figure 4: Example of Tags

Some of the RFID tags had been read through (RFIDTags. com, 2010), and the sort of tags will suit on this environment. For example:-

Avery Dennison Advertising-827 RFID Tag

This tag is one of smallest label in the RFID tags collection with strong and much longer read range ability and excellent stack performance. It was capable of getting, storing and transmitting digital information in multiple frequencies for supply string support. The Advertisement-827 provides strong read range which wills really helps to increase data level catch reliability although it is stack layout which sometimes will incorrect identified. It had been preferred in warehouse management, file management and library system which deal with traffic monitoring system.

Passive Integrator Transponder (PIT) Tags (Biomark, 2010)

Passive Integrated Transponder (PIT) has been used for forever identified individual pets or animals. PIT tags will detect the expansion rate, tendencies and health condition. In addition, it will capture the stress to the animal and minimizing handling time of RFID users.

5. 2Reader (Antenna)

An RFID Audience is a device which used to interrogate an RFID tags. Whereas the audience help as the middleman between your integration of label and coordinator system. It also can acquire data from RFID tags. It exchanges the radio waves from RFID tags into an application that can be used by middleware software. An RFID label reader uses antennas to talk to the RFID chip. Audience requirements was depending on the type of software and almost all applications will require more than one forms of readers to produce a successful system.

Reader used by different application will based on the consistency that the user to to make use of. (Control Electronic Company, 2004)

Below are a few of the image of reader such as mobile RFID audience(Ray Low, n. d):-

Figure 5: Exemplory case of Reader

5. 3Host Computer

All of the RFID reader communicate to a RFID coordinator processing through the cordless networking system. The variety will keep trail all the data and revise it as the data changes.

Figure 6 : Coordinator Computer

5. 4Printer

The purpose of Radio rate of recurrence printers is producing smart tags and brands. RF printers encode the data on RFID brands and tags while the same time they printing bar codes, printing text, graphics to be human readable wording.

Figure 7: Example of RFID Computer printer (Zebra RZ400)

5. 5Software (Middleware) (Shien-Chiang Yu, 2006)

RFID environment is demanding a middleware in order to implement it. Middleware is the software that allows the user to make the electronic identity link to creation or management information. The subject matter, data and information will be share with each others. Middleware software are had a need to manage the circulation of data from viewers and send the info to back-end management systems. Furthermore, Middleware will also helps in taking record, filtering data, retrieving data from viewers and generate inventory notifications.

Comparison between RFID tag and Bar code

RFID technologies just lately received attention from different area. Many consultants have stated that RFID will replace barcode as the keep track of and trace technology. By the same way, barcoding and RFID have emerged from the same origins, that is car recognition and both are bring information about product. In my opinion, RFID is not necessarily much better than barcodes as they are two different applications and contain different feature.

However, in many circumstances, RFID always offers advantages over traditional bar codes. Within the table below, you'll find so many evaluation have been carried out to be eligible the advantages of RFID and Barcoding technologies. (Atlas RFID Solution, 2010)

Characteristic

RFID Tag

Bar Code

Image

It have different kind of tags available. Besides, it have different size of the tags too.

Barcodes symbolized data in the lines and the spacing of parallel lines.

Line of Sight Requirement

Direct line of sight is not needed.

Any way can be focused by the items, as long as it is in the read range and there is no need to orientate scanned items.

It requires a direct line of perception to the branded barcode.

The items must be in physical form see by scanner each and every time it scan, and items must be focused in an exceedingly specific manner.

Read Rate (Atlas RFID solution, 2010)

Read rate for RFID tags considerably faster. As long as they can be within selection of a reader, RFID tags can be read.

Hence, it offers a larger system throughput by eliminate of manual operations or labour for repeated scans.

Inventory count up is very fast.

RFID can read multiple items together.

If the things aren't properly positioned to the reader, it might take time to learn an individual tag.

Reading barcodes is time-consuming because of the reason that immediate type of sight is required.

Very low throughput.

Tags can only be read by hand individually.

Read/Write Ability (Atlas RFID solution, 2010)

RFID tags have read/write devices and can truly add as much of the info as the label design will allow.

RFID in a position to read writes, enhance, and revise.

RFID reader can talk to the label, and get the information as the label design will allow.

Barcodes have no read/write capability; that means cannot add to the information written on a printed barcode.

It only find the money for read only.

Cost

RFID tags are more expensive but cost less as more market sectors choose the technology.

Implement Bar code is cheaper.

Durability (Atlas RFID solution, 2010)

It can be read through very harsh conditions as RFID tags are not affected by dirt. So, there is way better protected.

Tags may be positioned in extreme surroundings and perform based on the specification.

The readability of barcodes can be impaired by dirt, moisture, scratching, or packaging curves. Bar code can't be read if they become filthy or ruined during managing.

If a label is get mud or soiled or has dropped off, there is absolutely no way to scan the item successfully.

Data capacity/Data volumn

Provide additional item traffic monitoring info or even repair histories.

Can take relatively large level of data.

Physical limitation is present.

It is very hard to read a very long barcode.

Human capital (Atlas RFID solution, 2010)

Virtually do not require labor, the system is completely computerized.

Eliminate time/labor associated with relabelling items/resources over time.

Error free inventory count

Large labor requirements as laborers must check each label.

Require manual tracking and they are susceptible to human error

Security (Atlas RFID solution, 2010)

Security is high.

Difficult to reproduce.

Data can be encrypted, security password shielded, so information stored is a lot more secure.

Security is low.

Much much easier to reproduce again.

Event Triggering(Atlas RFID solution, 2010)

Can be utilized to result in certain function like gate openings, alarms, etc.

Bar code can't be used to cause events.

Dynamic updating

Tags may be written up to speed memory to retain information.

Updated may be produced automatically without real human intervention.

Old information can be over-written.

Once a club code is printed out it remains constant.

Cannot be updated

Below are the two amount show that the comparability time needed with its rate of recurrence between RFID and Barcode technology.

Figure 9. RFID using its consistency and time taken up to perform operation

Figure 10. Club Code Scanning with its occurrence and time taken up to perform operation

According to the physique above, Numbers 9 RFID show the difference between the times taken to perform the procedure by only using (9. 669 moments average) and Body 10 barcode scanning (24. 479 mere seconds average). (Gareth R. T. White, 2007)

This show that not only RFID is a faster operation but also more regular and give a specific picture that RFID can deliver faster scanning times than barcode scanning. This facilitates the view that RFID can deliver measurable functional benefits, faster circuit times cause more throughput, production benefits and lower product search time.

Application that can use RFID

Besides using RFID in inventory control system, there are other applications were also using on this. Since RFID technology is getting more popular, many business consultants experienced use the RFID tag to implement a few of their system. The advantage of using RFID have increase its utilization potential in creation, management system even security control also greatly benefited. Below are some of the RFID applications (Ray Low, n. d):-

Warehouse Management System

RFID technology offers a simple way to handle a huge and large making process. It includes the huge benefits such as reduce and eliminate bottlenecks, reduce any anomalies by alerting the staff, assists with better evaluation, reduced time in finding parts and products.

Security Control/Security Gate

Security gate are more common and we can see at any of shopping complex. It positioning at the shop exits and they read the security environment that is stored in RFID tags. The tags inside will determine if items are permitted to leave the shop. An security alarm sounds will band to alert staff if items never have been properly tested. In short, Security gate are incredibly useful in theaf detecting elsewhere.

Document Management System

This is most common problem in doc management system they can stored or take care of massive amount data and documents. The RFID document-tracking system saves lots of time and money by the way of minimizing time spent looking for lost record.

Library RFID Management System

In library by using RFID management system, RFID capable to read multiple items at the same time. This can escalates the range of customers and reduce queues that using self-check, that may reduce the staff necessary at the blood circulation desks.

Animal Micro chipping

RFID using microchip id on household pets by quicker and efficiently going back pets with their owners if they are lost. In pet animal, potato chips are usually put below your skin at the back of the neck on the pets or animals.

Linking to Project

Wang Wang Dog or cat Shop System is deal with sales order, hire and inventory control system. Therefore, the seminar name with RFID assist in inventory control can consider as linking to project. The primary related issue was inventory control management. RFID is a new technology that help a great deal of warehousing deal with their product and inventory by a powerful way. Through the use of RFID system, it can help Wang Wang Pet Shop to manage their product such as pet accessories by controling the inventory. However, there are extremely hard in utilizing the RFID system in to the project because the RFID system is a reallife technology. Hence, I am going to just propose the RFID notion and knowledge into my job.

RFID system can help on Wang Wang Dog or cat Shop by some ways. The product that we acquired was domestic pets and pet's accessories. RFID technology can control the inventory management with a chip or label inside the merchandise. The chip which put into the dogs can discover its family pet information such as years, breed, current healthier and their temparature. Whereas the chip which add in your pet accessories can identify the quantity degree of a particular product.

Next, batch processing can apply to the pet system by perform the inventory shelf-reading. RFID can offer assistance in tracing service. For example, personnel can immediately detect all of the collection within the number, including unnatural situation such as family pet accessories placed on the wrong shelf. Your, it can raise the efficiency of inventory and design.

Secondly, RFID can act as assistant of searching particular pet's accessories too. When member wishes to buy a pet accessory, the personnel no need find it all the way. The staff was just search it through computer by way of a click anyway. It could screen where is the merchandise located and the quantity left of the product. When you can find low of stock, the personnel will order again from company immediately. It reduce repeatable job of daily counting and verifying stock.

In final result, RFID system can tried to put into practice in Wang Wang Pet Shop system to help with keeping keep tabs on the inventory management.

9. 0 Critical Evaluation

Critical Evaluation

Before the end of this workshop, there are a few of the critical assessments has been reviewed. These include rational behind use of certain technique or tools, debate and thoughts and opinions about the technology.

Pros and cons of RFID system

The use of radio frequency to speak information among the system makes the inventory process faster. This capacity can help the manufacturer achieve the near future improvement by determine their inventory within hours rather than times. In my own view, RFID can really help warehouse in manage their inventory by an efficient way. Besides of using in inventory area, it also manages to help to increase shop's security. However, not absolutely all the applications of the technology and products are perfect atlanta divorce attorneys way. The only problem is that different RFID systems have different capacities and costs. The price depends on the application, the size of the set up, the reader and software cost and a great many other factors.

Comparison between barcode and RFID system

The function of both technology almost is identical to use to tracking data. The guarantee of RFID technology is the fact that it can improve almost company's workflow. However, some manufacturers still would prefer to use club code scanning because of its cheaper cost. On the other hand, RFID give a faster traffic monitoring data and eliminate labor cost. In my opinion, both technology have their quality and function it selves although everyone know RFID give more advantages compare to club code. RFID technology won't going to displace barcode system since both have their capacity and characteristic.

Hardware and software of RFID

With the execution of RFID system, the main component which include tags, reader, and software must be used. However, different hardware and software of RFID can be used in different environment. Some company used to print the RFID product labels and tags to become human readable word. While some warehouse will choose send the data to number computer without stamping the label away. It will have to is determined by the company whether they want what kind of outcome to be shown out.

10. 0 Conclusion

RFID is a comparatively a well known technology that is used by thousands of companies for a decade or more. It was mainly utilized for automated data collection that similar as barcode. RFID is easily integrated and optimize the info record and exchange. RFID will not depend on the orientation or line-of-sight and it can operate in a harsh industrial.

With the presence of tags, RFID visitors translate the air regularity information into digital information that can be read by software on the number computer. The computer decides the required actions and instructs the reader, which in turn transmits data back again to the label.

RFID technology definitely can help warehouse accurately manage selections and expand their services. For instance, RFID can be assistance in looking and orientation, make it a rapid inventory in warehouse. However, RFID will also face many issues such as costs, collision and security that become a hurdle to the warehouse management.

Thousands of companies worldwide have resorted RFID system to improve efficiency in creation as well as security features. For instance collection system, gate door for security goal, intelligent software agents are also used with RFID application to be able to automate usual decision-making.

For the issue on the comparison between RFID and pub code technology, in my opinion, RFID technology is not necessary much better than barcode. RFID technology will not going to replace barcode system since both have their ability and characteristic. There are two different systems and have different applications which sometimes can overlap.

In simple, RFID is talked about as the latest technology to help manage inventory problem face by all manufacturers. Not merely RFID been shown to provide benefits for the warehouse in its interior operation, its biggest contribution is on its capacity to improve information and materials flow throughout the entire warehouse.
