Overview The UniFinger modules are stand-alone fingerprint systems ideal for embedded system applications where biometric security is needed. The modules are designed for manufacturers searching for an inexpensive, reliable and easy-to-integrate biometric system. The UniFinger modules provide complete fingerprint solutions by incorporating fingerprint sensor interface and embedded fingerprint recognition algorithm into a half business card sized module. The UniFinger WFM1102 Module is the latest UniFinger module equipped with world’s leading fingerprint authentication algorithm (ranked No. 1 in FVC2004) and powerful DSP technology. Also, it supports wide range of fingerprint sensor interoperability giving you a freedom to select suitable sensor that most fits to your application. Furthermore, the fingerprint data for enrollment and verification are compatible among different sensors, even if they are based on different technologies. This feature of unification presents application manufacturers and system integrators with much more flexibility than ever before. In addition to these features, the miniature sized UniFinger module 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. The UniFinger stands ready to meet your requirements and adapt to your applications. Datasheet Copyright © 2004 by William,Inc. UniFinger WFM1102-FC 5 2.
