A portable electronic smart card for use as a medium for the dissemination among consumers of digitized data such as texts, pictures or game programs. The smart card is connected to user systems through a reduced set of contacts including, regardless of capacity, 3 contacts for transmitting address signals (CA1, CA2, INC/DEC), 8 contacts for transmitting data signals (D0-D7), and 5 different loading and control signals (VCC, VPP, GND, PGM, OE). For memory addressing, the card contains two up-down counters (11 and 12) which receive pulses from lines CA1, CA2 and INC/DEC. |
