This fingerprint sensor simplifies the process of fingerprint detection, storage, and verification. Inside the sensor is a high power DSP chip that does all image rendering, calculation, feature finding, and searching.
The sensor is relatively easy to use with any TTL capable microcontroller or system. Although this is not the exact same sensor, it is compatible with the fantastic tutorial Adafruit has put together (just note that the pinout from the connector is different!). There is also free Windows-based software available – this makes testing and viewing fingerprints very straight forward
You can also connect it with Arduino
