Word's smallest Fingerprinting + NFC and WiFi + BLE + USB wireless module!

With NFC + ESP32 enabled controllers not readily available, the creators behind the Chhavi decided to change that. 

The Chhavi is a touch-capacitive, wireless, NFC-enabled fingerprint sensor. 

According to the company, Chavvi’s open-source firmware works perfectly with Arduino IDE and features Fingerprints’ FPC BM-Lite fingerprint sensor that is accurate, tiny, and consumes low power.

Being wireless with a low power consumption, the Chhavi may be suitable for:
•    PC security 
•    Battery-based remote systems
•    Locking systems 
•    Attendance/personnel management 

Chhavi’s open-source files can be found in the public GitHub repo.
