First Claim
Patent Images
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, andwherein 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.

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. - View Dependent Claims (10)

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. - View Dependent Claims (12)
