Non-contact portable object comprising at least a peripheral device connected to the same atenna as the chip

摘要

A contactless portable object (10) featuring a main chip (12) and an antenna (14) enabling electromagnetic signals to be communicated between the chip and a reader associated to the contactless portable object, the antenna terminals being connected to the terminals of the main chip. The contactless portable object features at least one contactless peripheral device (16, 18), having a function different from the main chip, also connected in parallel to the antenna's terminals and whose energy required to operate is supplied by the antenna.
