Abstract
A portable article of the smart card type and a method of transmitting data to such an article. The article comprises an article body and an integrated circuit chip. The integrated circuit chip comprises a central processor unit (CPU) connected via a data and address bus to memories (ROM, RAM, EEPROM), and at least four contact pads (VCC, GND, RST, VPP, CLK, I/O, D+, D−) connected to four contact areas (C, C, C, C) of a set of at least six contact areas flush with the surface of the card body. Two of the contacts pads (D+, D−) are connected to an interface of the card and are suitable for providing data transmission handled by the central processor unit (CPU) such as for transmitting data using the universal serial bus (USB) protocols and formats.
