Optical Fingerprint Reader Sensor Module For Mega2560 R3 Raspberry Pi 3
Features:
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.

Note:
There are basically two requirements for using the optical fingerprint sensor. First is you'll need to enroll fingerprints - that means assigning ID #'s to each print so you can query them later. Once you've enrolled all your prints, you can easily 'search' the sensor, asking it to identify which ID (if any) is currently being photographed.
You can enroll by using the windows software (easiest and neat because it shows you the photograph of the print) or with the sketch (good for when you don't have a windows machine handy or for on-the-road enrolling)
