This SparkFun TTL Fingerprint Scanner (GT-521F32) does all of the heavy lifting behind reading and identifying the fingerprints with an onboard optical sensor and 32-bit ARM Cortex M3 processor. To get started, just register each fingerprint that you want to store by sending the corresponding command and pressing your finger against the reader three times.
The fingerprint scanner can store different fingerprints, and the database of prints can even be downloaded from the unit and distributed to other modules. In addition to the fingerprint “template,” the analyzed version of the print, you can retrieve the image of a fingerprint and even pull raw images from the optical sensor!
