Abstract
A RFID security structure for a document contains: a RFID antenna and a RFID chip. The RFID antenna is made of conductive inks printed on the document, and the RFID chip is attached on and is electrically connected with the RFID antenna. When the covering layer is removed from the document, the RFID antenna is broken. Accordingly, a portion of the RFID antenna attaches on the covering layer, and the other portion of the PRID antenna remains on the RFID security document or the substrate, hence the RFID security document is not tampered or is not imitated.
