Abstract
A micro-electronic component for a portable object is of the type which incorporates digital processing means, and an interface for contact-free electromagnetic coupling with a remote station. The digital processing means can operate according to an operating mode of the request/acknowledgement type, which is substantially insensitive to the propagation time, without a global, regular clock. The component additionally comprises adapter means, which can adapt the signals of the contact-free interface to the signals of the digital processing means and vice versa, in order to permit two-way dialogue with the remote station.
