Finger Print Sensor

A complete fingerprint system rather than just a sensor: it captures the image, extracts the template, stores it internally and performs the matching itself, then reports a simple result over serial. Your Arduino never handles biometric image data, which keeps both the code and the memory requirement small. Used in door locks, attendance systems and safes. Storage capacity is typically a few hundred prints depending on the model. Enrolment, storage and matching all handled onboard; Simple serial commands, minimal Arduino code; Fast matching, typically under a second; Stores hundreds of fingerprint templates
