  • Radio frequency data reader
    Patent number: 8035521
    Abstract: An RFID or NFC reader is associated via a data link with a tag module such that when the reader transmits an interrogation signal the tag module responds with a random, or constrained random, information signal. The information signal masks a signal transmitted by an RFID or NFC tag which the reader is interrogating, making fraudulently obtaining details contained in the tag transmission more difficult.
