I am building a door lock that we will use at a local MakerSpace-club in my city, and we had this idea about building a fingerprint lock with parts compatible with Arduino.
What we are aiming to do is create a database that holds all our customers and their associated information. Fingerprint data being one of them.
So my question is: Is it possible to have a fingerprint sensor store and compare fingerprint data with an external source such as a MySQL database, instead of using the on-board memory?
So basically: When a customer puts his finger on the sensor, the Arduino board grabs the fingerprint data and queries our database for a match through its WiFi shield. If match is found: Log entry and unlock the door.
Google is not helping me out here.
