METHOD AND SYSTEM FOR DETERMINING RFID TAG TAMPERING

摘要

The invention provides an RFID tag with means for determining when such tag has been tampered and means for securing the tag to an object. The tag may use an optical or infrared transmitter/receiver pair for detecting active tag removal from the object to which it is attached; and a method of attaching the tag holder to rounded objects regardless of object diameter while still preserving tamper capability of the active tag. Alternatively the tag may use an infrared radiation sensor to determine a change infrared radiation that occurs when the tag is removed from a person, and a light sensor to determine when tag has been tampered.
