Abstract
A contactless communication device includes an electronic integrated circuit chip and an antenna coupled to the electronic integrated circuit chip to supply an electric signal for powering the electronic integrated circuit chip. An ambient luminosity detection element is coupled to the electronic integrated circuit chip. An ambient luminosity level measured by the ambient luminosity detection element is supplied to the electronic integrated circuit chip for comparison to a darkness threshold. A contactless communication is authorized only when the measured ambient luminosity level is greater than the darkness threshold.
