Fingerprint access control is considered as the most reliable and secure access control method as every human being has distinct structures on fingers.In fingerprint access control, the fingerprint system first reads the print of the finger and matches it against the digital print image that has already been taken and stored in database.

The most common use for biometric access control systems like fingerprint access control system, is the history log. The ability to identify who entered a controlled area and when has proven to be a well appreciated system feature. Unlike security systems which rely of keys, a biometric access control will deter misuse as individuals will know that the access control system is recording their time and date of access. Hence, they are held accountable for their actions.When a person wishes to enter a controlled door, the access control system searches a database and establishes whether the person is authorised to enter or not. If the person is granted access, the system records the date and time of entry along with the identity of the person for future reference.
