Despite the fundamental differences in the sensing approaches, the main objective of a fingerprint scanner is to acquire a fingerprint image and provide it for enrollment or matching, as the case is.ĭifferent fingerprint solutions may leverage different approaches to store fingerprints. Reflected ultrasonic waves from ridges have a slight difference from reflected waves from valleys. More security-oriented implementations may use ultrasonic sound waves as a sensing mechanism in which, sound waves are projected on the finger skin and the reflected waves are detected to create a fingerprint image. Capacitive fingerprint scanners, on the other hand, use a grid of tiny capacitors to capture the ridge pattern image. For example, optical fingerprint scanners make use of visible light to capture fingerprint images with a digital camera. Fingerprint biometric devices may leverage different sensing technologies to capture the image. * Some readers on this list may also support contactless (NFC), but VA currently requires contact (inserted) cards for logical (computer) access.All types of biometric fingerprint scanners, regardless of the type and technology used, work by capturing a fingerprint image, extracting unique features, and comparing them with an already registered template.

The external smart card readers in the below table have been identified by IDEMIA as known to work with the new USAccess smart cards for logical (computer) access ( click here to identify the type of smart card you have been issued).

While these may work with appropriate drivers, VA recommends the purchase and use of an external smart card reader for all non-VA equipment. Some devices include an integrated smart card reader (such as laptops or keyboards). The SCR331 model may have been issued by the VA to users in the past. It should be noted that the SCR331 (not to be confused with SCR3310) readers DO NOT work with the newer smart cards nor on Macintosh computers. VA does not maintain an exhaustive list of smart card readers that DO NOT work.
