A smart card is a protected solution found in a closed environment, and thus is suitable for storing personal or secret information. In match-on-card technology, smart cards are used in the biometric user authentication procedure opposite the biometric template, which is created for them on the card during the issuing process. In this way, the verification level can be maximized with regard to card users, because it is the third factor – what is yours (card), what you know (the card’s password) and what is you (biometric template) – which cannot be bypassed or forged.


When the biometric authentication is made outside the card’s closed environment, the process is exposed to dangers. Communication between the card and the system authorizing the identification is likely to be unprotected. The biometric template could be manipulated – or copied. Perhaps even the decision to authorize or reject access will change because of it.

The match-on-card technology replaces the card’s password with a biometric element, but the card still remains responsible for protecting the process. And this way, the smart card itself provides authentication and not the remote system. This is the only way to really protect the information in the smart card.


In this technology, users control their biometric templates without dependence on a central database and thus they enjoy complete privacy regarding their biometric information. In addition, there is no more need to update the database like in the case of digital certificates or passwords.
Also if the card is stolen, the biometric information accumulated on the card is inaccessible, because it is stored and protected in the smart card and is only available to the person with matching biometric identity.
Linking MOC and PKI is a perfect combination where the smart card protects the private key while the biometric mechanism is responsible for true identification with the card.


The MOC solution creates a database suitable for every environment, and is easy to distribute, available and mobile – in all authentication mechanisms that are based on the smart card environment. The MOC solution is especially suitable for large organizations where establishing and maintaining a database are expensive operations.

The essence of the Precise solution

The biometric template is the biometric information representing the fingerprint that is created in the issuing process. This template includes two parts: A biometric header, which contains information about the type and version of the biometric algorithm in use; and the relative information, which contains the actual fingerprint template.

When an authentication process is performed, the authentication information is sent to the smart card. There it is compared to the ascribed template in order to create an identification rating, and according to this rating access is allowed or closed. The three stages can be seen in the following sketches:


Precise offers a number of integrated solutions, among which is the combined fingerprint and smart card reader.
