An identification card includes a fingerprint sensor, an antenna, a dual-mode radio frequency modulator connected to the antenna and digital circuitry having memory to store a digital word, the digital word including a representation of a fingerprint initially scanned by the fingerprint sensor to identify an individual associated with the identification card. The identification card further includes a control processor connected to the digital circuitry and the radio frequency modulator to communicate a signal to the antenna indicative of a successful match between the fingerprint initially scanned by the fingerprint sensor and newly scanned fingerprint. With such an arrangement, a technique is provided biometrically authenticating the identity of an individual passing through a checkpoint without requiring the individual to stop or exit a vehicle and eliminates the need for a central database of biometric data on individuals.
