Description 
Fingerprint Scanning technology is one of the most popular biometric modalities to verify the identity of individuals. The fingerprint matching compares the unique features such as the characteristics of ridges or minutia patterns that are found within the print pattern.
This is an optical biometric fingerprint reader/sensor with an R305 module and TTL UART interface for direct connections to a UART microcontroller. The user can store the fingerprint data in the module and can configure it in 1:1 or 1: N mode for identifying the person. This module can directly interface with any 3.3V or 5V microcontrollers, but a suitable level converter/serial adapter is required for interfacing with the serial port of a PC.
The fingerprint sensing process typically consists of capturing the fingerprint image, extracting the distinguishing features of the fingerprint, and then storing a digital template of the fingerprint or comparing the current image with the stored fingerprint templates.
