SunRobotics Fingerprint Scanner Detection UART TTL GT-511C3 Module  (Black)

GT-511C3 Finger print scanner module provides High-speed and Highly accurate Fingerprint Identification using the SmackFinger 3.0 Algorithm. The module is small and easy to mount using two mounting tabs on the side of the sensor. This is the updated version of the GT-511 which has an increased memory capacity. The module itself does all of the heavy lifting behind reading and identifying the fingerprints with an on-board optical sensor and 32-bit CPU.
