Cognaxon offers a free software, version 1.0, which is an NIST (ANSI/NIST-ITL 1-2000) viewer that can read and extract NIST (ANSI/NIST-ITL 1-2000) file formats.

For example, a WSQ file contains only one fingerprint image. However, one NIST file can contain multiple fingerprint images and additional information. ANSI/NIST-ITL 1-2000 is a data format defined by the American National Standard for Information Systems. This format is used for the interchange of fingerprint, facial, scar mark, and tattoo information.
One single NIST (ANSI/NIST-ITL 1-2000) file can contain various types of data, including transaction information, descriptive text, fingerprint image data, signature image data, minutiae data, facial and SMT image data, latent image data, tenprint fingerprint impressions, palmprint image data, and user-defined testing image data.
The NIST (ANSI/NIST-ITL 1-2000) viewer is a demo version of the NIST (ANSI/NIST-ITL 1-2000) library add-on. This add-on is available as an SDK for software developers. Overall, the NIST (ANSI/NIST-ITL 1-2000) viewer is a useful tool for anyone who needs to work with biometric data in a streamlined and efficient way.
