FS51 FIPS201/PIV can capture single finger, dual finger and roll
finger image. It was certified by FBI to be compliant with PIV-071006
Image Quality Specification (view PDF) for Single Finger Reader. So FS51 meets
the US Federal Information Processing Standard 201(FIPS 201) for
Personal Identification Verification (PIV) of Federal Employees and
Contractors. It is also listed in the US General Services
Administration (GSA) FIPS 201 Evaluation Program Approved Product List (http://fips201ep.cio.gov/apl.php).
A unique serial number is factory-programmed into the USB Device
Descriptor of each FS51. So every FS51 is traceable and this is very
important for government identity management projects.
