Biometric locks provide an entirely new level of interface with extreme ease & security. The most noticeable benefit is getting rid of carrying cumbersome keys. It also mitigates a range of problems associated with PIN, standard key, RFID, magnetic stripe cards, etc., while providing new levels of ease. Biometric door locks identify the authorized people on the basis of their biometric properties, already fed earlier into the system. The unique biometric characteristics of individuals allow only correct users to enter the system.

For quite some time the use of biometric access systems, particularly biometric door locks have been plagued by two flaws. First one has been the high cost of these devices in order to achieve accurate performance that put them out of the general consumer range. The second problem has been the visual design characteristics. But in recent years biometric device manufacturers have been able to sort out both these flaws. You can now find a range of biometric access devices in the market at an affordable rate.

Types of Biometric Technology
A number of identification technologies have been used by the biometric door locks manufacturers, such as fingerprint recognition technology, face recognition technology, voice recognition technology, iris recognition technology, etc. Each of these technologies work on some type of unique and individual biometric properties that we inherit. In this way one can't copy or duplicate one's unique identification like the password and access card, ultimately enhancing the security.

Unlocking Doors with Eyes
Now open doors with your eyes! You might have seen it many times in sci-fi movies. But the fiction has been changed to reality. Researchers from Queensland University of Technology's faculty of Built Environment and Engineering, has achieved sorting out one of the final obstacles to the everyday application of iris scanning technology. Already being used, this technology will become the part of our daily life in coming decade.

Like fingerprint every individual iris is unique and even the iris pattern of the left and right eye of the same person differs from each other. The iris pattern is fixed throughout a person's lifetime. Iris recognition confirms the identity of a person based on who the person is instead of what the person possesses, such as an ID card or password.
