Abstract
The light-emitting diode is provided with a lid and is capable of emitting a first predefined color. The card further comprises a near field communications antenna circuit, the circuit and the diode being configured so that the diode emits light when a current of predefined intensity flows in the circuit. More particularly, the lid of the diode is coated with a mass of material forming means for selecting a set of wavelengths from those making up the first color so that the light transmitted through the mass has a second predefined color different from the first color.
