Abstract

The card (40) is a plate in the form of a bank card which is provided with a power source, a microcontroller (144), a personal data memory (254), an acquired data memory (256), and a data-in-transit memory (212). Each card possesses two coupling members, i.e. a transmitter and a receiver on each of its faces, together with two manual activators (42-52) adapted to put it into operation. An operation of interchanging data between a plurality of cards (40.1, . . . , 40.4) comprises an initial step of checking feasibility in which a down stage during which the personal data in each card is accumulated (arrows 41.1, 41.2, 41.3) in the data-in-transit memories (212) of the cards disposed there beneath, and the other stage being an up stage symmetrical to the preceding stage. The end of this second stage triggers a down procedure in which the acquired data memories (256) are loaded. The last card in the stack issues an audible signal (58) to indicate that the operation has finished successfully. The card may be inserted in the appliance for making use thereof which is itself connectable to an external microcomputer, in order to display or process the acquired data, to modify the stored personal data, to enable or disable interchange thereof, or to apply a particular applications program thereto. Applications include intelligent calling cards and multipurpose cards.
