SDA04 is a complete, stand-alone fingerprint recognition system that captures and stores fingerprint data and identifies or verifies registered users. Designed to function entirely without an external PC, the SDA04 can be integrated into access control units, door locks and other products. It can communicate with external devices and is interoperable with data input from SecuGen USB fingerprint readers for a wide variety of implementations.
Technical Specifications | Developer Kit | Datasheet | User Guide
SDA04 uses next-generation fingerprint technology including SecuGen’s ruggedized, high image quality fingerprint optic module and high speed NIST MINEX Compliant fingerprint matching algorithms for fast 1:1 and 1:N search capabilities, and is FBI Certified as meeting FBI Image Quality Specs (IQS) and compliant with FIPS 201 standard for PIV Single Finger Readers.
