I would like to do an access control project. This means I have to control more than one door. I have been looking at the "Adafruit Optical Fingerprint Sensor" reader. I've been looking at examples and the documentation. I see that each reader stores the information internally. I'm not interested in that. The idea would be to have a shared DB on a server, for example in a MySQL DB, and every time a user puts their finger on a reader, I could check if that relative is registered in the shared DB. I am not interested in each user having to go to each of the fingerprint readers to register their fingerprints.
Does anyone have experience? Does anyone know of a business reader that would allow me to work as I would like?
Thanks.
Can you at least post a link to the sensor?
