Abstract
An apparatus (10) for capturing fingerprint images having a platen (21) sized for at most two fingers of a hand, and an imaging system for enabling capture of fingerprint images presented to the platen (21), in which images of two different finger pairs are captured for each hand of a subject when presented to the platen. At least one processor (27) which determines for each of the images captured a difference in height of at least one characteristic of the fingers in the image. Using said difference in height of the fingers in each of the images, the processor (27) verifies that the correct sequence of specific ones of finger pair was provided by the subject to the platen when images were captured. Fingerprint images acquired from the images may be stored in an electronic record along with thumb prints and subject information, and optionally the height differences for the images.
