Arduino + GT-511C1R(Fingerprint Scanner)

Hi guys,

I’m working on a arduino project that uses the GT-511C1R(Fingerprint Scanner) and the FPS only have 20 spaces for the fingerprints. I need to use much more than 20 fingerprints and don’t know how to export any fingerprint for a SD card, for example.

Any kind help is very appreciated. Thank you.
