Nothing new...... if you know about how RFID works, than this is just one of the way how to play with RFID CHIPS... this ID must be very expensive but doesn't mean anything... a better security solution can be done with cheaper budget. such as 3D face recognise, finger print, body DNA Sniffer, even a touch panel password input with random array will give you fantastic securely access control.
