Embodiments of the present invention implement dynamic elements within a RFID card. Specifically, the embodiments update card information dynamically, using a biometric image scanner (e.g., for scanning a fingerprint passively). The scanner is activated only when a user intends to use it with a designated reader by bringing the RFID card within the reader RF field range, thus preventing unauthorized reader's RFID scan. Even if an unauthorized reader comes into contact with the RFID card, the reader cannot read the user's biometric information, unless the user holds the card for use by the reader. Thus, unauthorized biometric information scanning is effectively prevented. The medium owned and controlled by the user collects a biometric fingerprint image for safety and security. When a card is swiped by the user, the biometric imaging array sensor captures user fingerprints and transfers the corresponding image data to a verification system to match and track user biometric information with a predefine accuracy, and track changes of repeated uses.
