Abstract

A method of providing an interface to a first application is disclosed. The first application is retained within a memory means (276) of an electronic card (100), with at least one of a plurality of user interface elements (154) being associated with a user interface element object stored in the memory (276). The memory means (276) is coupled to a processor means (275) of the electronic card (100). The processor means (275) is coupled to a reading device (300) configured to facilitate reading of the electronic card (100). The method executes at least a first application and a second application within the processor means (275). The second application is configured to associate reading signals generated by the reading device (300) in response to a selection of at least one of the elements (154) with a command to be issued to the first application. The second application is configured to provide the interface to the first application.

Claims

1. A method of providing an interface to a first application, said first application being retained within a memory means of an electronic card, with at least one of a plurality of user interface elements being associated with a user interface element object stored in said memory, said memory means being coupled to a processor means of said electronic card, said processor means being coupled to a reading device configured to facilitate reading of said electronic card, said method comprising at least the steps of executing at least a first application and a second application within said processor means, said second application being configured to associate reading signals generated by said reading device in response to a selection of at least one of said elements with a command to be issued to said first application, said second application being configured to provide said interface to said first application.

2. A method according to claim 1, wherein said at least one string includes a reference to said first application.

3. A method according to claim 1, wherein said second application is configured to store a sequence of user interface element selections within a first buffer of said memory means.

4. A method according to claim 3, wherein said sequence forms a portion of said command issued to said first application by said second application.

5. A method according to claim 1, wherein said reading signals comprise position information of said user interface elements on said surface, and said second application performs a mapping function to associate said position information with said command.

6. A method according to claim 1, wherein said first application is configured to store at least one of said retained data strings within a second buffer of said memory means in response to said reading signals.

7. A method according to claim 6, wherein contents of said second buffer are processed in response to a user selection of at least one of said elements.

8. A method according to claim 1, wherein said second application is configured to perform a secure access checking function for enabling or rejecting user access to a said first application.

9. An apparatus for providing an interface to a first application, said first application being retained within a memory means of an electronic card, with at least one of a plurality of user interface elements being associated with a user interface element object stored in said memory, said memory means being coupled to a processor means of said electronic card, said processor means being coupled to a reading device configured to facilitate reading of said electronic card, said apparatus comprising at least execution means for executing at least a first application and a second application within said processor means, said second application being configured to associate reading signals generated by said reading device in response to a selection of at least one of said elements with a command to be issued to said first application, said second application being configured to provide said interface to said first application.

10. An apparatus according to claim 9, wherein said at least one string includes a reference to said first application.

11. An apparatus according to claim 9, wherein said second application is configured to store a sequence of user interface element selections within a first buffer of said memory means.

12. An apparatus according to claim 11, wherein said sequence forms a portion of said command issued to said first application by said second application.

13. An apparatus according to claim 9, wherein said reading signals comprise position information of said user interface elements on said surface, and said second application performs a mapping function to associate said position information with said command.

14. An apparatus according to claim 9, wherein said first application is configured to store at least one of said retained data strings within a second buffer of said memory means in response to said reading signals.

15. An apparatus according to claim 14, wherein contents of said second buffer are processed in response to a user selection of at least one of said elements.

16. An apparatus according to claim 9, wherein said second application is configured to perform a secure access checking function for enabling or rejecting user access to a said first application.

17. A computer program for providing an interface to a first application, said first application being retained within a memory means of an electronic card, with at least one of a plurality of user interface elements being associated with a user interface element object stored in said memory, said memory means being coupled to a processor means of said electronic card, said processor means being coupled to a reading device configured to facilitate reading of said electronic card, said computer program comprising at least code for executing at least a first application and a second application within said processor means, said second application being configured to associate reading signals generated by said reading device in response to a selection of at least one of said elements with a command to be issued to said first application, said second application being configured to provide said interface to said first application.
