| 摘要 |
The invention relates to a communication interface (12,15;14,15) between a contactless smart card (11) imbedded in a communication mobile substrate (1) connected to a wireless communication network, and a contactless smart card reader (24) in the vicinity of the communication mobile substrate (1) and for radiofrequency communication with said contactless smart card (11), characterised in that it comprises, on the one hand, a first antenna (12; 14) provided on the contactless smart card (11) imbedded in the communication mobile substrate (1) and, on the other hand, a second antenna (15) attached to the communication mobile substrate (1) and connected by inductive coupling to said first antenna (12; 14) so that the contactless smart card (11) can directly communicate by radiofrequency with the contactless smart card reader (24) without using the wireless communication network.
