Abstract
An RFID anti-theft tag structure is disclosed. The RFID anti-theft tag structure includes a first protective layer, a paper sheltering layer, a permanent-magnetic alloy film, an RFIC, a sticky film, at least one alloy sheet, and a second protective layer sequentially disposed one on another from bottom to upper side. The alloy sheet can be repetitively magnetized and demagnetized. The permanent-magnetic alloy film and the alloy sheet are thus combined for cooperatively achieving the anti-theft function. The permanent-magnetic alloy film is divided into two independent portions, which are electrically coupled to the RFIC for serving as an antenna of the RFIC so as to achieve the RFID function. In such a way, the RFID anti-theft tag structure of the present invention integrally attains the anti-theft tag function and the RFID function, saves production cost and improves the convenience of use.
