Title: Identification card, sensor, and system

Abstract: The invention is an identification card that displays a finger or thumbprint pattern to confirm the user's identity. The card contains a sliding transparent window that slides from a concealed, non-use position to a visible position where the user can place his fingerprint on the window. When the window slides from the visible position to the concealed position, a wiper in the card cleans the residual print from the window.
