Description:

RFM72 is new generation of fingerprint modules for time attendance, access control, lock and safe devices. RFM72 utilize optical fingerprint sensor, which consists of high-performance DSP, high-capacity flash and color CMOS sensor.

RFM72 includes all intelligent modules for fingerprint image processing, template generation, template matching, fingerprint searching, template storage etc. This product has professional developed and designed optical fingerprint sensor, hardware circuit and fingerprint algorithm created. The self-owned intellectual property gives the RFM72 a high performance-price ratio.

Function:

• Big Capacity 3000 fingerprint, small template – 496byte, quick identification time
• Support fingerprint template update automatically
• Support pressure sensor function, when the finger put on the module, the wakeup pin will output +V signal.
• Support download fingerprint from RFID card, then compare the fingerprint with the template.
• Sleep/awake controlling for lower consumption application
• Users can define different security levels according to different application
