Abstract

A method for activating a user interface of a mobile terminal or device having an ISO14443 smart card attached in a ISO7816 reader, where the mobile device monitors the state of the inactive ISO7816 interface, the ISO14443 smart card changes the state of one or more of the ISO7816 contacts when it needs user interaction during contactless communication, and when a state change occurs that did not originate in the mobile device, an interrupt is generated that communicates to the mobile device that smart card requires its services.

Claims

1. A method for establishing an interaction between a mobile terminal and a smart card arranged therein, characterized in that the smart card provides an interaction command signal to the mobile terminal to initiate the interaction.

2. A method according to claim 1, characterized in that the interaction command signal includes a change in the state of one or more contacts between the mobile terminal and the smart card.

3. A method according to claim 1, characterized in that the smart card provides the interaction command signal during a contactless connection with another device.

4. A method according to claim 1, characterized in that the one or more contacts are a part of a galvanic connection.

5. A method according to claim 1, characterized in that the mobile terminal responds to the interaction command signal and generates an interrupt signal to establish the interaction.

6. A method according to claim 1, characterized in that the smart card provides the interaction command signal during a contactless connection with another device.

7. A method according to claim 6, characterized in that the one or more contacts are a part of a galvanic connection.

8. A method according to claim 7, characterized in that the mobile terminal responds to the interaction command signal and generates an interrupt signal to establish the interaction.

19. A method according to claim 2, characterized in that the smart card provides the interaction command signal during a contactless connection with another device.

20. A method according to claim 19, characterized in that the one or more contacts are a part of a galvanic connection.

9. A method for establishing an interaction between a mobile terminal and a smart card arranged therein, characterized in that during a contactless communication the smart card changes a state of one or more contacts of a galvanic connection between the mobile terminal and the smart card to initiate the interaction.

10. A method according to claim 9, characterized in that the mobile terminal responds to a change in the state of the one or more contacts and generates an interrupt signal to establish the interaction.

11. A method according to claim 9, characterized in that the mobile terminal activates an interface with the smart card and runs a query to find out what services the smart card requires.

12. A method according to claim 9, characterized in that the mobile terminal monitors the state of the one or more contacts and filters out state changes that happen when the interface between the mobile terminal and the smart card is active.

13. A method according to claim 9, characterized in that either the mobile terminal, the smart card, or both is in an inactive mode.

14. A smart card for arranging in a mobile terminal and having one or more contacts for establishing an interaction therewith, characterized in that the smart card has an interaction command module for changing a state of one or more contacts to initiate the interaction between the mobile terminal and the smart card.

15. A smart card according to claim 14, characterized in that the one or more contacts are a part of a galvanic connection between the mobile terminal and the smart card.

16. A smart card according to claim 15, characterized in that the interaction command module changes the state of the one or more contacts during contactless communication with another device.

17. A mobile terminal having a smart card arranged therein, characterized in that the mobile terminal has a media control unit module that responds to an interface command signal from the smart card containing information about a change of state of one or more contacts between the mobile terminal and the smart card, generates an interrupt signal, activates an interface with the smart card, and runs a query to find out what services the smart card requires.

18. A mobile terminal according to claim 17, characterized in that the media control unit modules monitors the state of the one or more contacts and filters out state changes that happen when the interface between the mobile terminal and the smart card is active.
