Adafruit Fingerprint Sensor info

Adafruit Fingerprint Sensor will make adding fingerprint detection and verification super simple. These modules are 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.

Adafruit Fingerprint Sensor is a great choice because not only is it easy to use, it also comes with a fairly straight-forward Windows software that makes testing the module simple - you can even enroll using the software and see an image of the fingerprint on your computer screen. The best part of the sensor is the full Arduino library written by Adafruit. Using the library, you can get running in under 10 minutes. The library can enroll and search so it is perfect for any project. There is also a detailed tutorial written by Adafruit on wiring and use. Adafruit Fingerprint Sensor is by far the best fingerprint sensor you can get.
