Mikroe Fingerprint 3 Click is used to interface a compatible Fingerprint Sensor with Two-Color LED Ring with the host MCU. The board allows for securing projects with a biometric all-in-one fingerprint sensor that will simplify fingerprint detection and verification. The Fingerprint 3 Click can be implemented in various applications. It can be embedded into end products like access control, attendance, or safety deposit box to integrate biometric security into designs.
