Abstract

A communication link is established between the smart card and a computer using a valid smart card communication protocol. A smart card communication device determines the valid smart card communication protocol used by a smart card by polling a communication channel using a plurality of smart card communication protocols until a valid acknowledgment message is received. A radio frequency circuit is configured to communicate with the smart card using the valid smart card communication protocol. A digital signal processor having at least two demodulators demodulates an incoming data stream produced by the receiver in accordance with the valid smart card communication protocol in a dynamically reconfigurable manner.

Claims

1. A system for communicating with a plurality of smart cards, each smart card of the plurality of smart cards having a communication protocol of a plurality of smart card communication protocols, the system comprising:

at least one smart card communication device for establishing a radio frequency communication channel with the each smart card;

at least one master module coupled to the at least one smart card communication device, the at least one master module for establishing a secure communication channel between the at least one master module and the each smart card using at least one security device located within the at least one master module; and

a central computer system coupled to the at least one master module through a communication network, the central computer system for periodically receiving a transaction information from the at least one master module, and for periodically sending valid smart card numbers to the at least one master module.

2. A system as in claim 1, wherein the communication network is one of an Internet, a public switched telephone network, a private branch exchange system, a cellular telephone system, a personal communications service system, and a point to point microwave system.

3. The system as in claim 1, wherein the at least one smart card communication device is configured to poll for a valid smart card communication protocol by sequentially transmitting a plurality of initiation messages, each of the plurality of initiation messages using a one of the plurality of smart card communication protocols, and identifying the valid smart card communication protocol upon receipt of a valid acknowledgement message.

4. The system as in claim 1, wherein the at least one security device within the master module comprises a security device configured to encrypt and decrypt data for communicating with a Type A smart card.

5. The system as in claim 1 wherein the at least one security device within the master module comprises at least one Security Access Module.

6. A system as in claim 1, wherein the at least one smart card communication device further comprises:

a demodulator for demodulating an incoming radio frequency signal transmitted from the each smart card to produce an incoming bit data stream;

a modulator for modulating an outgoing bit data stream transmitted from the at least one master module to produce an outgoing radio frequency signal; and

a micro-controller for arranging the incoming bit data stream into a plurality of incoming data packets, and for appending a header to at least one packet of the plurality of incoming data packets, the header including information indicating a security device type.

7. A system as in claim 6, wherein the at least master module further comprises:

a master module controller for removing the header from the at least one packet to produce incoming data at the at least one master module; and

a switch for routing the incoming data to the at least one security device based on the security device type included in the header.

8. The system as in claim 1, wherein the at least one smart card communication device comprises:

a transceiver configured to establish the radio frequency communication channel with the each smart card; and

a digital signal processor coupled to the transceiver and configured to perform modulation and demodulation in accordance with the plurality of smart card communication protocols, the digital signal processor further configured to be reprogrammed to add an additional smart card communication protocol.

9. The system as in claim 8, wherein the at least one smart card communication device further comprises a micro-controller configured to control the digital signal processor to a particular smart card communication protocol from the plurality of smart card communication protocols.

10. The system as in claim 1, wherein the master module is configured to communicate to the at least one smart card communication device one or more polling parameters comprising types of smart cards to be polled and predetermined wait periods between successive polls.

11. The system as in claim 10, wherein the polling parameters further comprise a polling sequence parameter configured to instruct the at least one smart card communication device to poll rare smart card protocols less frequently than other smart card protocols.
