Abstract

A communication system including a first transceiver having a user identification; and a second transceiver having the same user identification as the first transceiver, wherein the first and second transceivers operate in tandem.

Claims

1. A communication system comprising:

a first transceiver having a transceiver identifier and a first set of memory addresses of a first memory configured to store data; and

a second transceiver having the same transceiver identifier as the first transceiver and a second set of memory addresses of a second memory configured to store data, the second set of memory addresses being at a predetermined offset with respect to the first set of memory addresses,

wherein the first transceiver supports a first set of application protocol data units (APDUs), and the second transceiver supports a second set of APDUs having no APDUs in common with the first transceiver, and the first and second sets of APDUs conform to ISO 14443 and/or 15693, and

wherein the first and second transceivers are operable as a single transceiver and the first and second memories are operable to appear within the communication system as being a single, physical memory when transmitting to another transceiver.

2. The communication system of claim 1, wherein the first and second sets of memory addresses have no addresses in common.

3. The communication system of claim 1, further comprising one or more additional transceivers having the same transceiver identifier as the first transceiver.

4. The communication system of claim 1, wherein the first and second transceivers are contactless transceivers.

5. The communication system of claim 4, wherein the first and second contactless transceivers are contactless communication cards.

6. The communication system of claim 1, wherein the first and second transceivers are contact-based transceivers.

7. The communication system of claim 1, wherein the first transceiver is a contactless transceiver, and the second transceiver is a contact-based transceiver.

8. The communication system of claim wherein at least one of the APDUs is a security APDU.

9. A communication system comprising:

a first transceiver having a transceiver identifier and a first set of memory addresses of a first memory configured to store data;

a second transceiver having the same transceiver identifier as the first transceiver and a second set of memory addresses of a second memory configured to store data, the second set of memory addresses being at a predetermined offset with respect to the first set of memory addresses,

wherein the first transceiver supports a first set of application protocol data units (APDUs), and the second transceiver supports a second set of APDUs having no APDUs in common with the first transceiver, and the first and second sets of APDUs conform to ISO 14443 and/or 15693; and

a reader configured to communicate with the first and second transceivers,

wherein the first and second transceivers are operable as a single transceiver and the first and second memories are operable to appear within the communication system as being a single, physical memory when transmitting to a reader.

10. The communication system of claim 9, wherein the first and second transceivers are contactless communication cards.

11. A method of configuring a contactless communication system, comprising:

reading a contactless card identifier of a first contactless card having a first set of memory addresses of a first memory configured to store data; and

configuring a second contactless card to have the same contactless card identifier as the first contactless card and to have a second set of memory addresses of a second memory configured to store data, the second set of memory addresses being at a predetermined offset with respect to the first set of memory addresses,

wherein the first contactless card supports a first set of application protocol data units (APDUs), and a second contactless card supports a second set of APDUs having no APDUs in common with the first contactless card, and the first and second sets of APDUs conform TO ISO 14443 and/or 15693; and

wherein the first and second contactless cards are operable as a single contactless card and the first and second memories are operable to appear within the communication system as being a single, physical memory when transmitting to a reader.

12. The method of claim 11, further comprising:

configuring the first contactless card to be mute when the second contactless card is communicating with a reader.
