Smart card access control system
First Claim
1. A system for providing controlled access to a secured area, the system comprising:
- a secured device for allowing access into the secured area upon receiving at least one access control signal;
an identification device for providing identification data corresponding to a biometric measurement by the identification device;
an access card having at least one block of memory comprising;
application data corresponding to biometric data of an access card holder; and
at least one application security key comprising an application read key; and
an access reader for outputting the at least one access control signal for controlling the secured device, the access reader comprising;
a memory means for storing configuration data and at least one valid security read key;
an RF interface for reading the application data from the access card if the at least one valid security read key is the same as the application read key, the at least one valid security read key providing an authenticated reading of the application data from the access card;
at least one input data line for receiving the identification data from the identification device; and
a processor means for comparing the application data to the identification data and for outputting the at least one access control signal upon a match between the application data and the identification data.

Abstract
An access control system securely transfers identification and transaction information between an access reader and a contactless smart card over a contactless radio frequency link via an RF modem. The access reader contains a programmable microcontroller, DC/DC converter, regulator, Opto-Isolators and LEDS, and an RF modem. The smart cards contain identification or transaction data as well as reader programming and de-programming software, which is protected by appropriate security keys. An access reader having the appropriate security keys performs a one to one verification of data stored in the smart card to data from an identification device coupled to the access reader. Upon verification of the validity of the smart card, the access reader transfers identification and transaction information over a data link to any external processor or controller which controls access to a secured area. Both the data format/protocol and operating state out of the access reader is programmable and configurable at any time. The access reader and access cards are compatible with any existing Wiegand, magnetic stripe, and serial based access control systems, and are configurable to emerging Biometric system designs.

13. A method of controlling access to a secured area using an access reader, the method comprising the steps of:
-
receiving identification data corresponding to a biometric measurement of a user of an access card from a biometric device; reading application data corresponding to biometric data of an access card holder from an access card, comprising the steps of; transmitting an application read key from the access reader to the access card; and allowing output of the application data from the access card if the transmitted application read key matches a read key stored on the access card; comparing the application data to the identification data; and outputting at least one access control signal upon a match between the identification data and the application data, the at least one access control signal for allowing access to the secured area. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A system for controlling access to a secured area, the system comprising:
-
an access card configured to; store, in memory of the access card, biometric data of an access card holder and an application read key; prevent output of the biometric data to one or more access devices until a security read key matching the application read key is received; and output the biometric data to the one or more access devices when the security read key matching the application read key is received; and the one or more access devices, communicatively coupled with the access card, and configured to; read the biometric data from the access card only when the application read key matches the security read key stored in memory of the one or more access devices; receive identification data corresponding to a biometric measurement associated with a user of the access card; compare the biometric data with the identification data; and output at least one access control signal to allow the user access to the secured area upon a match between the biometric data and the identification data.
