RFID-www.js6038.com is an antenna and a chip that we call a tag. Another antenna is linked to a reader which in turn is linked to a computer that allows you to read and write information on the tag. Our technology helps librarians eliminate valuable staff time spent scanning barcodes while checking out and checking in borrowed items. It also allows patrons to avoid queuing at counters where the barcodes are scanned. Instead they go to a self-checkout station that issues the book and deactivates the anti-theft technology in the chip. For the patron, RFID speeds up the borrowing and returns procedures. The Librarians, instead of scanning bar codes all day long in front of a queue of patrons, are released for more productive and interesting duties. RFID also helps with inventories. We offer portable solutions with a PDA linked to an antenna and a reader that allows an inventory of millions of books to be completed in several hours. Without RFID it would take several librarians several months to complete.

Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 920MHz and 925 MHz, also known as the decimetre band as the wavelengths range from one meter to one decimetre. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is high enough for indoor reception. Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored information. Passive tags collect energy from a nearby RFID reader's interrogating radio waves. Active tags have a local power source such as a battery and may operate at hundreds of meters from the RFID reader. Unlike a barcode, the tag need not be within the line of sight of the reader, so it may be embedded in the tracked object.
