What is a Swipe Fingerprint Reader/Sensor?
A Swipe Fingerprint Reader/Sensor requires the user drag the upper part of the finger across the sensor. The complete image is pieced together by accumulating the partial image as the finger moves across the scan area. Pros of a Swipe Fingerprint Reader/Sensor: • Smaller imaging array • Cheaper – It requires a smaller IC chip, which significantly reduces the overall sensor cost • Swiping motion reduces contamination buildup on the sensor, which is particularly a problem for optical sensor. Cons of a Swipe Fingerprint Reader/Sensor: • Less accuracte – Dynamic swiping may decrease the accuracy due to increased distortion of the finger surface as it is pulled across the sensor. • Swiping creates additional wear on the sensor surface • More difficult to use.
