Abstract: A method and a system for establishing communication between an object (200), a user device (100) and a service device (300). The method comprises the steps of transmitting a communication request signal to an object identifier (210) associated with said object (200); and receiving a response signal from said object identifier (210). The response signal includes an identification of said object (200) and information describing a communication capability of said object (200). Further in the method, the communication between the object (200) and the user device (100) is established using this communication capability. Further in the method, a service request signal is transmitted to said service device (300). The service request signal includes information representing an identity of the user device (100) or an identity of the object (200). The service request results in the service device (300) transmitting a service provision signal to the user device (100) or the object (200).

Abstract: The invention relates to a subscriber identity module for a mobile communication terminal, comprising a processing device, a memory device, an I/O device and a wireless communication device, in particular an interrogatable transponder such as an RFID transponder. The RFID transponder is operatively controllable by said processing device, and comprises a memory which contains identification data, configurable by the processing device. The RFID-enabled subscriber identification module may be used as an authentication token. A method for providing secure communications between the subscriber identification module and an RFID interrogating device is also provided.
