For use in verifying the identity of a user, an identity verifier comprising an optical fingerprint sensor coupled to an ID (identification) card reader. In one embodiment of the present invention, the optical fingerprint sensor includes a light source on a PCB assembly, a diffuser that receives light from the light source, a right angle prism that receives light from the diffuser, a collimating lens that receives light from the prism, a first mirror that receives light from the collimating lens, a second mirror that receives light from the first mirror, a third mirror that receives light from the second mirror, an imaging lens that receives light from the third mirror, and an image sensor on the same PCB assembly as the light source that receives light from the imaging lens. In one embodiment of the present invention, an ID (identification) card reader reads an ID card that contains biometric information about the user, and compares the biometric information on the card with the fingerprint of the user captured by the optical fingerprint sensor captured by the optical fingerprint sensor.
