Abstract
The invention concerns a multi-frequency transponder for communicating at a first frequency according to a first communication protocol and at a second different frequency according to a second communication protocol. The transponder comprises a first physical memory for storing a first data of the first communication protocol; a second physical memory for storing a second data, different from the first data, of the second communication protocol; and a logic unit for accessing the first and second physical memories. The logic unit comprises a first control unit for handling communications according to the first protocol, and a second control unit for handling communications according to the second protocol. The transponder comprises a mapping memory to store a logical memory map of the first or second physical memories. The logical memory map comprises mapping information for the first or second control unit to access data items in first and second physical memories.
