Abstract:
1. A communication mobile substrate, comprising: a communication interface for communications between a first contactless smart card housed in the mobile communications substrate connected to a wireless communications network, and a contactless smart card reader, the interface comprising: a first antenna located on the contactless smart card; a second antenna integrated in the communication mobile substrate; and a third antenna, integrated in the communication mobile substrate and separate from the second antenna, configured to communicate with the wireless communications network; and a slot and a receptacle for the introduction of a second contactless smart card, said second contactless smart card being positioned in the electromagnetic field of the second antenna and being able to receive and to execute an application program involving a communication with the contactless smart card reader through the second antenna, wherein the first antenna and the second antenna are inductively coupled such that the first contactless smart card can communicate directly with the contactless smart card reader via the second antenna without using the third antenna or the wireless telecommunication network.
