Optical Fingerprint Reader Sensor Module (LACC200640) [S078]

https://www.youtube.com/watch?v=IG0DRWpI0nY

* Specs

Make adding fingerprint detection and verification super simple.

Typically used in safes­-there's a high powered DSP chip that does the image rendering, calculation, feature-finding and searching.

Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash and search.

You can also enroll new fingers directly - up to 162 finger prints can be stored in the onboard FLASH memory.

There's a red LED in the lens that lights up during a photo so you know it is working.
