摘要：
The invention concerns a method for data transmission between an electronic smart card (4), a terminal such as a computer (1) and a user, said smart card comprising a central processing unit (CPU) connected via a data bus and addresses to storage units (ROM, RAM, EEPROM) and comprising an assembly of eight bond pads electrically connected to corresponding contact pads borne by the smart card. The invention is characterized in that the central unit exchanges data with said terminal (1) in accordance with universal serial bus (USB) standard through first and second contact pads (D+, D-) and in that the central unit communicates data to the user through a third contact pad (I/O) connected to specific visual or audio communication means (6).
