From GEOVISION, the GV-GF1922 Fingerprint Reader works with the GEOVISION GV-ASManager software and accompanying controllers to create a complete access control system. (Standalone mode is also available.) Three types of operation modes are supported: card only, fingerprint only, and card plus fingerprint modes. Fingerprints are enrolled over a TCP/IP connection via GV-ASManager in fingerprint only mode. The reader supports GEOVISION access cards with GID (GEOVISION Identifier).
