Method and apparatus for acquiring access using a smart card
First Claim
1. A method for using a smart card to gain access through an access device upon payment of a value (V), the method comprising the steps of:
- operatively coupling said smart card to said access device;
reading at least a first set of data and a second set of data from said smart card;
performing a first authentication process on said at least first set of data;
permitting access if said step of performing a first authentication process meets a required condition;
storing said at least first set of data and said second set of data in a memory of said access device; and
performing a second authentication process on said at least first set of data and said second set of data after said step of permitting access is accomplished.

Abstract
A method for using a smart card to gain access through an access device upon payment of a value (V) is performed by first operatively coupling the card to the access device. The access device reads a first and a second set of data from the card, and performs a first authentication process on the first set of data. Access is permitted if the first authentication process meets a required condition. Access is denied otherwise. If access is permitted, the second set of data is stored in the access device for further processing, including a second authentication process which operates on the first and second sets of data.

10. An access system, including:
-
an interface device, having contacts for coupling with a smart card to read at least a first and a second set of information; an access device, coupled to said interface device, having at least a first processor for performing a low-level authentication of said at least first set of information received from said smart card; a memory in said access device, storing said at least first set of information and said second set of information; a gate device, coupled to said access device, said gate device granting access to a cardholder after said low-level authentication is performed; and at least a first security module, said first security module being in communication with said access device, wherein said first security module is arranged to perform a high-level authentication of said at least first set of information and said second set of information received from said card after said at least first set of information received from said card and stored in said memory. - View Dependent Claims (11, 12, 13, 14, 15)

16. An access control system, comprising:
-
a plurality of card reading devices, each having a contact structure for reading at least first data and second data from a smart card; a plurality of access devices, coupled to said card reading devices, for performing a low-level authentication on said at least first data from said smart card, said access devices having a memory for storing said at least first data and said second data from said smart card; and a terminal device, coupled to said plurality of access devices, for performing a high-level authentication on said at least first data and said second data from said smart card after said at least first data and said second data are stored in said memory of said access devices. - View Dependent Claims (17)
