Fingerprint scanner GT-511C3: All fingers are removed suddenly
Posted: Tue Nov 13, 2018 1:34 pm
I am using Fingerprint scanner GT-511C3 with Adafruit feather for my project. Everything works perfectly but I found registered fingers are removed suddenly after giving some one. They have no access to code level but only a product I made. How could this happen? Any possible scenario and solution to prevent this issue later?
