Biometric techniques to date have been successfully implemented in the areas of fingerprint recognition, voice test, iris scanning, signature or rubric, hand geometry, face geometry and genetic identification (DNA), among others which are in development or test phases.

Unlike physical objects related to security as keys or magnetic cards, or logical objects such as passwords or PINs, which can be stolen, borrowed or copied the relatively easily-biometric characteristics are unique and not transferable, no one can give or lend someone the fingerprint, the iris of the eyes or their genetic code, or at least not in agreement and many biometrics devices are available at http://www.timeclockeshop.com.

This makes this technology suitable for solving problems related to control access to physical locations (buildings, laboratories, confined spaces, safety boxes), or, computer security (user authentication, access to restricted documents).

Among these applications, there is an economically important: biometrics is also used for the “time and attendance control” for the companies to avoid the use of passwords or cards that employees can easily misplace or forget. Continue reading →
