  Radio frequency identification (RFID) is a technology that employs basic
identifier of an object embedded in a chip, transmitted via radio wave, for
identification. An RFID Card responds to query or interrogation irrespective of
"Who" holds the Card; like a key to a door. Since an attacker can possess the
card, access to such object can therefore be easily compromised. This security
breach is classified as an unauthorized use of Card, and it forms the bedrock
for RFID Card compromise especially in access control. As an on-card
authentication mechanism, this research proposed a concept termed Bio-Thentic
Card, which can be adopted to prevent this single point of failure of RFID
Card. The Bio-Thentic Card was fabricated, tested and assessed in line with the
known threats, and attacks; and it was observed to proffer substantive solution
to unauthorized use of RFID Card vulnerability
