Operates with a single 3.3v dc supply, or unregulated power, such as batteries
Integrated power control circuit
Overview
The SFM modules are designed for manufacturers searching for an inexpensive, reliable and easy-to-integrate biometric system. The modules provide complete fingerprint solutions by incorporating fingerprint sensor interface and embedded fingerprint recognition algorithm into a half business card sized module.
The SFM4000-TS4 is the latest SFM module equipped with Suprema's world-leading fingerprint authentication algorithm and powerful DSP technology. It supports a wide range of fingerprint sensor interoperability giving you the freedom to select the most suitable sensor for your application. The fingerprint data for enrollment and verification are compatible with different sensors, even if they are based on different technologies. This presents manufacturers and system integrators with more flexibility than ever before.
In addition to these features, the SFM has a state-of-the-art low-power design making it a perfect match in a wide range of applications from battery-operated mobile equipments to network-based security systems. With internal regulator, dual voltage configuration, and power control features, the SFM4000-TS4 offers flexible configuration to maximize design simplicity and reduce time to market.
