MATA BioTech has developed a biometric door lock designed to recognise the authorised userís fingerprint in order to open a door, making conventional keys unnecessary.
The company says the M28 is easily installed on just about any standard door. Simply place your finger on the door lock and in less than 3 seconds, it recognizes the user and permits access if allowed.
A fingerprint sensor is connected to a microprocessor inside the lock. The information from the scan is analyzed and if verification of the fingerprint is successful, the lock mechanism opens allowing the user to turn the handle and open the door. Initially, a fingerprint is scanned and enrolled right on the lock, and it is instantly converted into a mathematical template. This template is a data representation of the fingerprint. It is stored in the memory of the lock, and later used during verification.
The M28 Fingerprint Door lock can store up to 10 fingerprints, and can enroll and delete individual fingerprints from its memory without having to erase all stored fingerprints. All the operation is done right on the lock, without the need of a computer link. As a fail safe, three identical mechanical keys are included to manually open the door if needed.
The lock is powered by four standard AA alkaline batteries and battery life is 8 months to a year depending on usage. When the battery power is low, the unit produces an audible warning signal. When the batteries are removed and replaced, the enrolled fingerprints remain in memory.
