The invention relates to a communication method comprising the following
steps consisting in: using a device which is equipped with at least one
antenna and at least two contacts which are connected to the antenna;
using a chip card comprising a chip which is equipped with at least two
surface contacts, a processing module and a radio frequency interface
which is associated with said processing module and which is connected to
the surface contacts of the card, the surface contacts of the card being
connected to the contacts of the device; and transmitting electric
signals between the surface contacts of the card and the antenna. The
invention can be used, in particular, to increase the communication range
of the chip card. The invention also relates to an associated chip card
and device
