Add biometric security to your next Arduino project

Arduino TeamJune 2nd, 2016

If you’ve ever wanted to add biometric security features to your Arduino project, you’re in luck. That’s because Nick Koumaris of has put together a quick tutorial on how to integrate a fingerprint sensor module with an Arduino Nano and a 1.44” color TFT display.

The fingerprint sensor module is small, nicely built, and it uses some advanced DSP (Digital Signal Processing) chips inside. The sensor works like this. It is an optical sensor, which means it analyzes the photo of a finger. It then renders the image, makes some calculations, finds the features of that finger and then searches in its memory for a fingerprint with the same characteristics. It can achieve all that in less than a second! This module can store up to 1,000 fingerprints in its memory and its false acceptance rate is less than 0.001% which makes it pretty secure!

As you can see in the video below, the project requires a valid fingerprint in order to unlock. If it recognizes the user, which in this case is Koumaris or his girlfriend, the fingerprint icon on the display turns green along with a kind greeting, e.g. “Welcome, Nick!”
