Abstract
An RFID system and tag, and a method for identifying objects using an RFID system are disclosed. In an embodiment, an RFID tag comprises a microchip for storing an identification sequence, a tag antenna coupled with the microchip for receiving and transmitting the RF signal; and a ferrous metal portion disposed near the IC and the tag antenna. The ferrous metal portion is sensitive to, and heats up when subjected to, magnetic induction. The heat of the ferrous metal is propagated to the RFID tag such that the tag reaches its operating temperature more quickly.
