An RFID system consists of a tag that is attached to a library item. This tag houses a microchip with a very small antenna and has data embedded on the chip. A reader with a larger antenna generates electromagnetic, or radio, waves. The small antenna on the tag is tuned to identify and respond to these waves. When the frequency transmitted by the reader matches the tuned frequency of the tag, the tag draws power from the radio waves and broadcasts the tag's saved data. The reader picks up this transmission and sends it on to be converted into useable digital data by the library's Integrated Library System.
WHY RFID IS HOT
Wal-Mart's push to use RFID in the open supply chain is a big reason why the technology is hot today. But it's not the only reason. Several important factors have come together around the same time. One is the advances in ultra-high frequency (UHF) RFID systems. UHF systems are able to deliver the read range needed for supply chain applications, such as scanning tags on products as pallets are moved through a dock door or scanning cases on a high shelf in a warehouse. Another factor was the efforts by the Auto-ID Center to develop a system that is low cost and based on open standards. These are prerequisites for the use of RFID in open supply chains, where a
