Because the template is stored in the card, the verification is performed between the data in the card and the live template from the reader, rather than from the controller. If a match is found, the reader sends to the controller the access control information that is stored in the card. The whole process is simplified. This architecture can accommodate any biometric technology, but the key is that it works in conjunction with access control data. The challenges are then to develop a very sophisticated enrollment process and to be able to freely program the smart cards.
This solution enables companies to leverage biometrics and smart cards for multiple security purposes. The smart cards can be used as universal credentials, for not only physical security but for IT security as well, to log into computers and provide user authentication into networks.
