Abstract
A contactless smart card imbedded in a communication mobile substrate connected to a wireless communication network, and a contactless smart card reader in the vicinity of the communication mobile substrate for radiofrequency communication with the contactless smart card, are disclosed. On one hand, a first antenna is provided on the contactless smart card imbedded in the communication mobile substrate and, on the other hand, a second antenna is attached to the communication mobile substrate and connected by inductive coupling to the first antenna, so that the contactless smart card can directly communicate by radiofrequency with the contactless smart card reader without using the wireless communication network.
