Radio-Frequency Identification (RFID)
RFID architecture works like a small area (generally in few meters) client-server network based on radio frequencies for communication between client and server. It has two component RFID Client Tag and RFID server or antenna or receiver, RFID tag is applied or incorporated into an object or a product for the purpose of identification and tracking using radio waves. RFID tag is an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, and other specialised functions. The receiver or antenna is for receiving and transmitting the signal. D Server preceiver There are generally three types of RFID tags.
1. Active RFID Tags - contain a battery and can transmit signals autonomously.
2. Passive RFID Tags - Have no battery and require an external source to provoke signal transmission.
3. Battery Assisted Passive(BAP) - Require an external source to wake up but have significant higher forward link capability providing great read range.
Among the many uses of RFID equipments, one is its implementation in libraries. This technology has gradually begun to replace the conventional barcodes on library items. The RFID tag can contain many identifying information, such as a book's title, author's name, publication year, publisher name, book type, etc. This information is read by an RFID reader, which replaces the standard barcode reader. The RFID tag used on products or library materials typically measures 50 mm X 50 mm. It may replace or be added to the barcode to provide an innovative and easier way for other inventory management also. It can also act as a security device, taking the place of the more traditional electromagnetic security strip and not only the books, but also the membership cards could be fitted with an RFID tag.
