This is an RF solution, and is not an RFID solution. RF and RFID are different. RF is mainly Electronic Article Surveillance (EAS) System. You cannot store/add information/data to the Non-deactive tags. However, RFID tags are readable/writable. Hence, advantages are more: o EAS System o Simultaneous Check-in/Checkout of more than one documents is possible o Self-Checkout and Self Check-in without compromising security is also possible. o Automatic sorting of returned documents is also feasible o Misplaced documents can be traced o Not necessary to continue with barcode. -- Arup Raychaudhury _____________________________________________________________ Indian Statistical Institute |Phone: 91-33-2575 2106/2100/2118 203 B.T.
