RFID CORE TECHNOLOGY At the simplest terms, RFID is a technology that utilizes radio waves for communication between a transmitter and a receiver. In the event of RFID for company, the recipient is a reader/antenna and the transmitter is a label. The label is encoded with a special identification number. This amount is transmitted to the reader everywhere the tag is queried. The special ID number can then be referenced in a database for extra information regarding the labeled item. Any RFID system is made of two major components: hardware, software/database. The hardware consists of tags, reader and antennas. The software consists of middleware and also a database containing a list of all encoded tags and also at least one first cross reference for the label. There are a wide variety of tags available on the marketplace. Depending on the label, the operating frequency range will be at 125 khz, 13.56 mhz, 915 mhz, 2.45 ghz or 5.8 ghz. A label is intended to operate in only 1 frequency range. Tags are available in a wide range of styles and shapes. Tags have limited read ranges. Label type, style and frequency is dictated by structure of the item to be labeled, overall environmental conditions where the tag must function, and the range at which the tag has to be read. Tags can be divided into two main groups: passive and active. While the definition of every group continues to evolve, there's an simple definition which helps to separate the 2 groups. Active tags have a built-in electricity source (i.e. Battery) and also will broadcast their signal to readers. Passive tags don't have a built in power supply. Instead passive tags await a reader's signal to reach them and provide power to the tag. The passive tag will then use the signal in the reader to get powe...
