Abstract
A method and an apparatus for upgrading an existing personal control system. The upgrade is achieved by replacing the personnel data input unit of an existing personal control system with a biometric interface device capable of reading physical characteristic and an access control signal in the format of the existing personnel control system.
Claims8
An apparatus for interfacing with an existing personnel control system that utilizes stored data in a predetermined format for the purpose of determining whether a presented individual is authorized to have access to a controlled area, the apparatus comprising:
- means for storing physical characteristic information for a plurality of individuals;
- means for storing for each individual, an access signal associated with the existing personnel control system;
- means for scanning a physical characteristic of a presented individual;
- means for generating a scanned physical characteristic signal for the presented individual;
- means for comparing the stored physical characteristics information to the scanned physical characteristic signal to determine if a match is found;
- means for outputting the access signal associated with the presented individual when a match is found;
- and
- means for communicating the outputted access signal to the existing control system in a format that is compatible with the predetermined format of the stored data so that the existing personnel control system will recognize the outputted access signal as a match for the presented individual stored data and authorize access to the controlled area.
The apparatus of clam 1 wherein the predetermined format of the existing personnel control system is compatible with information stored on a card.
A biometric apparatus for interfacing with an existing personnel control system that utilizes stored data, in addition to biometric data, for the purpose of determining whether a presented individual is authorized to have access to a controlled area, the apparatus comprising:
- means for storing biometric information for a plurality of individuals;
- means for obtaining biometric information on a presented individual;
- means for storing for each individual, an access signal associated with the existing personnel control system;
- means for generating an obtained biometric information signal for the presented individual;
- means for comparing the stored biometric information to the obtained signal to determine if a match is found;
- means for outputting the access signal associated with the presented individual when a match is found;
- and
- means for communicating the outputted access signal to the existing control system in a format that is compatible with the stored data so that the existing personnel control system will recognize the outputted access signal as a match for the presented individual stored data and authorize access to the controlled area.
