Introduction Barcodes are used everywhere . They are utilized to track products through shipment, track products in a shop and speed up and enhance the checkout process, in addition to allowing quicker access to information. Barcodes started to be used heavily in the 1970's. This began a wonderful movement in the consumer industry, speeding up the checkout process and allowing easier inventory tracking. But exactly like all technology, barcodes have been enhanced many times over and are being replaced by much better, more efficient systems (Bonsor). RFID, or radio frequency identification, is the new system that's replacing the use of barcodes. RFID tags allow users to more quickly obtain information from the object that the RFID tag describes (Evans, 2012, p. 190). RFID tags are more useful and will gradually replace barcodes entirely because they allow the user to scan the object without physically touching or optically reading anything on it. As opposed to studying an identification number that's then looked up in a database, it's possible to gather information directly from the label (Bonsor). How It Works RFID is a technology that's been developed, upgraded, and improved since the year 1970 (Bonsor). The technology has advanced, making it simpler, usable, and more effective. RFID uses radio waves to transmit data from an RFID label to an RFID reader. These radio waves are much like those that are broadcast through wireless networks but are normally shorter range (What's RFID, n.d.). There are two main types of RFID tags: active and passive. The difference between these two types lies within how and when they transmit their stored data. An active RFID tag is related to a power source, ge...
