Les sytèmes biométriques et leur utilisation pour les contrôles d'accès

The use of the hand's geometry is the most popular method employed for the access control particularly to the USA. In France this technique is not used very often. Indeed, it requires a special tray, having guides to position fingers, rather cumbersome.

However biometrics by the shape of the hand is a popular technology which is largely employed for the physical access control or the time pointing. It is a very simple and cheap system.
The element used for the identification is only the hand geometry and not on the palmar print.
The reader of the contour of the hand offer a very reasonable level of exactitude, but can have high rates of false acceptances raised for twins or other members of the same family.
