Biometric Door Lock
Biometrics has become a very important word today in home and office security services. Yes, devices like the biometric door lock that work on fingerprint recognition are no longer sci-fi gizmos today. The fiction has become a reality. Now, you can easily use your fingerprints to open locks at home and your office that gives you a monumental amount of convenience. The best benefit definitely is that you won't need to rely on your keys anymore. You won't have the nagging fear that you have misplaced your key to your home when you are out and keep checking your pockets to ensure they are there.
The biometric door lock works by recognizing your fingerprints and opens. Indeed, when you use this kind of lock, you are actually having your keys as a part of your body, which are your fingerprints themselves!
These locks have a sensitive reader panel where your fingerprints can be read. When you need to open the lock, all you have to do is place your finger on this panel. If you have stored your fingerprint in the memory of the door lock, it will immediately snap open, allowing you to open the door. This is quite a convenience when you are back home from a shopping trip and are carrying a lot of packages.
Modern biometric door locks can store a lot of fingerprints. There are some locks that can store up to seventy five fingerprints. All these people would have access to the door. But you, being the main owner of the lock, can decide who you want to give the access of the lock to. These people will need to feed their fingerprint information into the memory of the lock and then they can open the door when they wish. There are also locks that provide you to give just one-time access to certain visitors, after which their fingerprint information will be wiped off from the memory of the device. But even with the multiple access fingerprints, you, the owner of the lock, can delete whichever fingerprints you want to, thus barring them access. Fingerprints are the most popular method of recognition in biometric door locks today, but you must not think that these are the only methods. Biometrics actually means identification through a trait that a person has with them. Fingerprints are definitely the commonest traits, but there are locks developed that can identify faces, retinas, ear canals and even odors of people. At the same time, you must not think that the biometric door lock is the only device that uses the biometric technology. There are several other devices, of which the most common are the biometric time and attendance devices uses in most companies today track the work hours an employee puts in, which can go a long way in deciding their payroll. This device is also known as the biometric time clock. However, the biometric door lock is a very cheap device that can provide an immense security to the home. They run on batteries, and usually spare batteries are provided. Also, there are mechanical overrides if the device ever fails to function.
