Hand scanner works by creating and storing the templates of hand geometry in a biometric device, which are later used for identification and verification processes. Used mainly as employee attendance clocks, these devices have completely changed the scene of business organizations. Due to its association with biometric technology, a hand reader is capable of providing accurate results.
Among all the biometrical technology, fingerprint-based identification is the most widely used in security applications; simply, everyone has their unique, immutable fingerprints. Commercially, fingerprint matching is one of the most efficient to authenticate an authorize entry, access to confidential data. Fingerprint matching techniques falls into two categories: minutiae-based and correlation based. Minutiae-based techniques find the minutiae points and then mapping them on the finger. The shortcoming of this method is difficult to extract the minutiae points accurately if the fingerprint is of low quality. Whereas, correlation-based techniques need the precise location of a designated point and a image translation. There are difficulties in either method; therefore, developing fingerprint modules for different security devices is very crucial in the industry.
