9. A radio frequency identification (RFID) system comprising:
-
an RFID reader associated with an interrogation zone to interrogate RFID elements, wherein the RFID reader detects RFID elements respectively associated with a patron card and an item when the patron card and the item each enter the interrogation zone, and modifies a status of the item with respect to a patron associated with the patron card when the patron card enters the interrogation zone substantially simultaneously with the item; and
a database, wherein the RFID reader updates the database to reflect the modified status of the item. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
