Abstract
The microcircuit card (10) comprising a body (12) delimiting an edge (14) of the card (10). The body (12) incorporates a luminous means (16) capable of illuminating at least partially the edge (14) of the card (10).
Claims13
A microcircuit card comprising a body delimiting an edge of the card, said card comprising:
- a luminous means inside the card configured to illuminate at least partially said edge of the card, light emitted by the luminous means being transmitted in a thickness of the body up to said edge by way of a transmission region of the body made of a first material and surrounded at least partially by a second material different from the first material, the first and second materials constituting an optical waveguide for said light;
- and
- first and second near-field communication antennas connected respectively to the microcircuit card and to the luminous means;
- wherein the first near-field communication antenna is configured to supply power to the microcircuit card and the second near-field communication antenna is configured to supply power to the luminous means;
- and
- wherein the body consists of a stack of layers, the transmission region constitutes one of the layers of the stack which is a central layer interleaved between at least two external layers made of the second material.

- and
- an external power supply contact directly connected to the luminous means and operable to draw power via contact with an external contact type card reader, said contact extending over the card;
- wherein the body consists of a stack of layers, the transmission region constitutes one of the layers of the stack which is a central layer interleaved between at least two external layers made of the second material.
