Fingerprint Acquisition Profile (FAP) number is levels for optical capture devices that can be used for fingerprint capture. The FAP level is based upon device capture dimensions, the image quality specification applied, and the number of simultaneous fingers that can be captured.

ANSI/NIST and the FBI classify mobile ID fingerprint scanners with a fingerprint acquisition profile (FAP) based on the following:
• Scanner capture area dimensions;
• Image quality specifications (IQS);
• Number of fingerprint impressions captured simultaneously.

The FBI further categorizes mobile ID fingerprint scanners as follows:
PIV-071006: a certification standard for scanners designed to primarily support one-to-one verification; and
• Appendix F: a certification standard with strict image quality requirements for scanners
that can support large-scale, one-to-many matching.

Table 1-0 details the FAP requirements. Single finger scanners have an FAP rating of 30 or below, and are primarily used for verification and identification. Scanners of FAP 40 and above may be used for enrollment, as well as one-to-one and one-to-many searches. They are capable of capturing more than one finger simultaneously and typically include the option to collect rolled impressions as well as the required flat impressions. However, rolled impressions capability is not required for mobile ID.
