Biometric Scanner Used In Passport As Well As The Visa

Biometric Scanner is now being used in passports and visa for easy identification of citizens. This actually prevents fraud and entry as well as exit of criminals or those still being detained for security reasons.

It is actually based on an approach called cognitive biometrics where it uses fingerprints, face or facial recognition and others and linking it to an already existing computer database. So the computer database matches the fingerprints, hand, in some cases, even the eye for identification of the individual. So it does not take a genius for one to figure out why it is being used in passport and visa.

Aside from using Biometric Scanner in passport as well the visa, it is also used by companies. Companies are now changing their bundy system or their time clocks to something more complex and automated such as the fingerprinting method for identification and security, timekeeping and key to the offices. This is a very useful method as only employees hired by the company will be the only ones who will be able to gain access to company property. A couple of years from now, even security guards who screen every employee and visitor will no longer be needed by companies because of this technology.

If you will come to think of it, the biometrics scanner used now is still shallow if they will just base it on fingerprints or facial recognition. There will come a time when all the aspects of the human being both physiological as well as behavioral will be used by embassies for passport and visa and companies for recognition of employees as well as for security purposes. Samples of physiological biometrics are face, fingerprint, hand, iris and dna. While we can be identified via the use of behavioral biometrics with our keystroke, signature and voice. If this were to happen, the possibilities will be endless, not only for passport and visa processing and use but also for the other systems that we use daily such as grocery shopping. We no longer need to bring money but we can pay with our thumbprint and it will automatically debited to our account. Or we no longer need to bring our identification cards to work as we can use our voice to gain access to the work place.
