Abstract
An activated contactless communication circuit includes a device for receiving and transmitting a data-carrying electromagnetic field; a first circuit resonating with a first antenna for receiving data; and a second circuit resonating with a second antenna for transmitting data, the first and second resonating circuits being separate from each other. The transmission is carried out at a frequency phase-synchronized with the frequency of the electromagnetic field for reception.
