Abstract
A device having a card (40) and a support (PC). The card has (a) no internal battery, (b) a single antenna (10) that receives electromagnetically data and power, (c) a data processor, (d) rectifying and filtering circuitry receiving the electromagnetic input and supplying at output terminals (A, B) a voltage to the processor. and (e) two terminals (36, 38) on an external surface of the card which are connected to the output terminals (A, B). The support is mechanically and electrically connectable to the card. It has (a) a power source that may be a battery, (b) surface terminals that mate with the card'"'"'s external terminals, (c) a switch for connecting the power source to the surface terminals, and (d) a mechanism for holding together the card and support with the card'"'"'s and the support terminal'"'"'s electrically engaged to one another.
