Abstract
Abstract One aspect of the present invention is a method and apparatus of providing a card and/or reader that recognizes a communication mode of a corresponding reader and/or card. The card reader comprises a memory and a card interface circuit to detect a mode of a card. A processor coupled to the card interface circuit and the memory, communicates with the card in the detected mode if the detected mode matches a communication mode of the processor. The card comprises a memory and a reader interface circuit to detect a mode of a reader. A processor coupled to the reader interface circuit and the memory, communicates with the reader in the detected mode if the detected mode matches a communication mode of the processor. Another aspect of the present invention is a method and apparatus of providing a card and/or reader that is operable in two communication modes. The dual mode card reader comprises a memory and a card interface circuit to detect a mode of a card, the mode being one of first and second communication modes. A processor coupled to the card interface circuit and the memory, communicates with the card in the detected mode. The dual mode card comprises a memory and a reader interface circuit to detect a mode of a reader, the mode being one of first and second communication modes. A processor coupled to the card interface circuit and the memory, communicates with the reader in the detected mode.
