Abstract
A method for assisting a user of a fingerprint sensing system includes sensing a position of a user's finger relative to a swiped fingerprint image sensor, and providing to the user, in response to the sensed finger position, an indication of finger placement relative to the fingerprint image sensor. The indication of finger placement may include a display on a computer monitor of actual finger placement and desired finger placement. The fingerprint sensing system may include an image sensor to sense a fingerprint on a swiped finger, a finger position sensor to sense the position of the finger relative to the image sensor, and processing apparatus to provide the indication of finger placement to the user.
