<p>A portable data carrier comprises at least one miniaturized circuit having several memory sections, means for transferring data between the carrier and a data transfer device manual setting means on the surface of the carrier for presetting program elements in the miniaturized circuit, a display window fox displaying data in humanly readable form, a first single button for placing an n- digit decimal number into a first variable memory section of the miniaturized circuit, and circuit means for enabling an operator to effect this operation while receiving visual feedback from the display window. The carrier can serve as a long-life multiple account pay token. The purpose of producing a long-life multiple account pay token is gradually to reduce the demand of coins and bank notes thereby lowering the high cost of minting and printing them. In parallel therewith, the relatively high cost of operating cheque accounts by Banks shall be reduced.</p> |
