<p>An apparatus 1 and methods for implementing registration and/or invalidation of RFID tags is disclosed. An RFID reader 2 receives an RFID signal including an instruction to register or invalidate (cancel), which is transmitted from an operation tag 10b in a recognition area (A). Depending on the signal the apparatus sets an operation mode to registration-enabled or invalidation-enabled. Subsequently when an RFID tag recognizer (31a) recognizes an authentication tag 10a, the apparatus will either: a) register the authentication tag as part of a group; or b) invalidate or cancel the authentication tag itself, or all authentication tags that belong to that tags group. The methods allow easy invalidation of an authentication tag when it has been lost or stolen, and facilitates management of authentication tags for new employees or residents, for example for gaining access to a building.</p> |
