The biometric technology has an ever-growing in access applications domain where the identification or verification accuracy is essential for security. The success of the implementation depends on the proper recognition system for specific application, realising the best solution concordantly demanded security standard.

The biometric technology property to realise a link between an individual and a transaction or action, offers the advantage of unwanted unauthorized person usage, excluding eventually system fraud.

A card system can control but can not make the link between the card and the individual and the card can be lost, borrowed or duplicated. The PIN systems presume that one individual knows the specific code that authorize the acces, but still there is no link between the PIN and individual.

The biometric technology removes all these disadvantages which makes an administrative efforts reduction. For example one lost or damaged card presumes a new enrollment process. When the number of this kind of events grows, the card administration is expensive.
