Abstract
A serial-port memory is positioned in a substantially token-shaped body. The substantially token-shaped body has a perimeter and a flange extending from a portion of the perimeter. The serial-port memory comprises a serial port, a scratchpad memory coupled to the serial port, a second memory coupled to the scratchpad memory; and control logic coupled to the serial port and the scratchpad and second memories. The control logic transfers information from the scratchpad memory to the second memory as a block pursuant to a block transfer command received at the serial port. The electronic token has a first electrically conductive surface and a second electrically conductive surface that combines to create a hollow cavity and the serial port, scratchpad memory, second memory, and control logic positioned inside the hollow cavity, the first conductive surface and the second conductive surface can be electrically coupled to transmit electrical signals generated by the serial port, scratchpad memory, second memory, and control logic and to receive externally generated electrical signals. The first electrically conductive surface and the second electrically conductive surface are preferably…
