Now by putting a finger over fingerprint module, we can check whether our finger prints are already stored or not. Operation of this project is simple, just run the python code and there will be some intro messages over LCD and then user will be asked to Place Finger on Finger Print Sensor.

Complete Python code is given at the end of this project. Step 4: After installing library now we need to check USB port on which your finger print sensor is connected, by using given the command. Step 3: After this, we need to update the Raspberry pi and install the downloaded finger print sensor library. Step 2: Then download some required packages by using given commands. So first we enter in root by given command. Step 1: To install this library, root privileges are required. Now we need to install fingerprint library for Raspberry Pi in python language by following the below steps.

A 10k pot is also used with LCD for controlling the contrast of the same. So, first of all, we need to make the all the required connection as shown in Circuit Diagram below.Ī 16x2 LCD is used for displaying all messages. Here we have used a fingerprint module which works on UART. Complete working of the system has been shown in the Video given at the end of article.Ī LED is used for indication that fingerprint sensor is ready to take finger for matching. Using this Raspberry Pi FingerPrint System, we can enroll new finger prints in the system and can delete the already fed finger prints. Finger Print Sensor, which we used to see in Sci-Fi moives few years back, is now become very common to verify the identity of a person for various purposes.
