How To Select Types of Biometric Devices

Have you ever seen modern-day spy movies, where doors are never simply locked and bolted, but protected by all kinds of high-end devices? Way cool, right? Another cool thing is that these high-tech locks and security devices are real, and are actually accessible. Locks like these, which open only once they have determined some certain unique physical characteristics of the person to be a match to their records, are widely used as a sure protection against thievery and larceny.

The effectiveness of biometric technology comes from the fact that each human being possesses certain characteristics that are uniquely his or her own. These characteristics include fingerprint patterns, retinal patterns (or the pattern of the blood vessels found at the back of the eye), voice pitch and facial contours. As no two persons have the same fingerprint pattern, biometric identification and biometric authentication could be used to read, say, a person’s fingerprints using a specialized scanner, and to determine whether that person is indeed authorized to enter a room or to access the things inside that locked area.

Biometric devices typically use fingerprint and retinal scanners above anything else, since these two human characteristics are the hardest to replicate. These patterns reputedly have 99% foolproof rating.

What are some of the applications of these biometric devices? Apart from security, they are also used in biometric attendance applications; that is, instead of having the employee use time cards, they could have their fingerprints scanned on special devices. This is advantageous since they won’t have to carry around their ID’s or time cards in order to register their attendance. There’s absolutely no danger that they’d forget to carry around their fingers! Plus, it’ s an advantage to their employer since there’s less chance for the employees to ever defraud the biometric device. 

If you’re interested in buying biometric technology, one of the first routes you could go about with your search would be online. Some of the websites you could try out would include You would be able to find different types of biometric devices here, including fingerprint readers (at about $100). At, read up on nifty biometric security options available in flash drives (where you can open files only if the flash drive recognizes the fingerprint to be your own) and hard drives. Biometric flash drives cost $60 to $220 depending on the memory size, while biometric hard drives cost around $220 to $600.

Of course, try out reliable trading sites like,, and for their offered biometric technology and biometric software. The best thing about trying out this avenue is that you could easily compare prices on different brands, plus you’d probably be able to score a used but still high-quality model.

There you have it! These are just some of the places where you can start searching for biometric security devices. Remember, sometimes it just pays to be paranoid, and the extra money you’ll pay for the extra security may well be worth it.
