Abstract
A scanning fingerprint detection system that includes an array of capacitive sensing elements. The array has a first dimension greater than the width of a fingerprint and a second dimension less than the length of a fingerprint. Each of the capacitive sensing elements has a size less than the width of a fingerprint ridge. Circuitry is provided for scanning the array to capture an image of a portion of fingerprint and for assembling the captured images into a fingerprint image as a fingerprint is moved over the array.
