Abstract: The identification and security system is for an item (10) particularly a data storage disk, CD, DVD, etc. being borrowed by system user (11) from a library. The item comprises a data storage disk (16) mounted in a storage case (20). RF transponder means (25, 30) are mounted by the item (10) to provide identification data and security data with the data being readable from RF signals transmitted by the transponder means in response to external interrogation signals. The transponder means comprises a first RF transponder (25) which is a relatively smaller sized transponder, particularly an RFID transponder tag mounted in the annular space (18) between the central hole (17) and the inside diameter of the data storage area (19) of the disk (16). A relatively larger size transponder (30) provides improved detectivity due to the larger size.

Abstract: A library monitoring system includes a number of borrowable items. Each item has a radio frequency identification device mounted thereon and the radio frequency identification device has a unique identification code. A processing unit is coupled to a database containing an indication of the location of each library item and is coupled to a borrowing location, a borrowed item returning location and the returned item sorting location. The borrowed item returning location includes a receptacle into which the borrowed item is inserted. The receptacle includes an antenna which detects an insertion of library item having a radio frequency identification device mounted thereon. The borrowed item returning location responds to the insertion of a library item into the receptacle detects the identification code and sends the identification code corresponding to the returned library item to the processing unit.
