Abstract: This concept which is of Fingerprint door locker is related to the security issues in the day today life, the physical key can be made as duplicate in very cheap cost and the key can lost somewhere or the key can steal, to overcome these issues we can use biometric security gadgets and try improvise the security much more because it can never be stolen it cannot be lost and the stealing chance of duplication are very low to break the security. Here we will use fingerprint for biometric verification as it is one such thing which is unique to every individual.

Keywords: Biometric, Arduino, Sensor, Identification, Locking system.
