Local radio-frequency communication interface for e.g. mobile telephone, has antenna connected to another set of antennas to allow smart card communicating with non-contact reader without using wireless telecommunication network

摘要

The interface has antennas (12, 14) arranged on a contactless smart card (11) i.e. subscriber identity module card, and integrated into a mobile communication support (1) e.g. mobile telephone, which conforms to global system for mobile communications (GSM). Another antenna (15) is integrated with the mobile communication support and connected to the antennas (12, 14) by inductive coupling to allow the smart card directly communicating with a non-contact reader (24) by radio frequency without using a wireless telecommunication network.
