Abstract

An electronic card (100) configured to be read by a reading device (300) is disclosed. The card (100) comprising a card portion (270) having a surface (156) onto which are formed a plurality of user interface elements (154) and electronic apparatus (259) attached to the card portion (270). The apparatus (259) comprising a memory (276) in which are retained a plurality of data strings. At least one of the data strings is associated with a corresponding one of the user interface elements (154). The apparatus (259) also comprises a processor means (275) coupled to the memory means (276) and communication means (278) for coupling the processor means (275) to the reading device (300). The processor means (275) is configured to relate reading signals generated from a selection of at least one of the elements (154) and received via the communication means (278) with at least one of the retained data strings. The retained data strings are inaccessible to the reading device (300).

Claims

1. An electronic card constructed to be read by a reading device, said electronic card comprising:

a card portion having a plurality of user interface elements on a surface; and

an electronic apparatus on said card portion, said electronic apparatus comprising;

a memory retaining data, wherein said retained data is associated with a corresponding one of said user interface elements;

processor means coupled to said memory; and

communication means for coupling said processor means to said reading device, wherein said processor means associates a selection of one of said user interface elements with said retained data and uses the association to perform a secure access checking function for enabling user access to a desired service,

wherein said selection is provided by a substantially transparent touch sensitive membrane of said reading device arranged to overlap said electronic card, wherein said membrane is responsive to pressure applied anywhere on the membrane, and wherein respective positions of the user interface elements are independent of predetermined positions on the membrane.

2. An electronic card according to claim 1, wherein said processor means generates an output signal according to said retained data based on said selection.

3. An electronic card according to claim 1, wherein said selection generates corresponding position information of said user interface element, and said memory and processor means perform a mapping function to associate said corresponding position information with said retained data to thereby interpret said selection.

4. An electronic card according to claim 1, wherein said retained data in said memory is processed in response to said selection.

5. An electronic card according to 1, wherein one or more of said plurality of user interface elements correspond to a personal identification number.

6. An electronic card according to claim 1, wherein each of said plurality of user interface elements correspond to one or more images on said surface.

7. The method according to claim 1, further comprising the step of generating an output signal according to said retained data based on the mapping.

8. A method of transmitting information based on a mapping of data retained in a memory of an electronic card with position information generated by a reading device configured to read said electronic card, said electronic card comprising a card portion having a plurality of user interface elements on a surface, wherein said retained data is associated with a corresponding one of said user interface elements, wherein said memory is coupled to a processor means, and wherein a communication means couples said processor means to said reading device, said method comprising the steps of:

transmitting a selection of one of said user interface elements from said reading device to said processor means via said communication means; and

associating said selection with said retained data using the processor means; and

using the association to perform a secure access checking function for enabling user access to a desired service,

wherein said selection is provided by a substantially transparent touch sensitive membrane of said reading device arranged to overlay said electronic card, wherein said membrane is responsive to pressure applied anywhere on the membrane, and wherein respective positions of the user interface elements are independent of predetermined positions on the membrane.

9. The method according to claim 8, wherein said selection generates a corresponding position information of said user interface element, and said memory and said processor means perform said mapping in order to associate said corresponding position information with said retained data to thereby interpret said selection.

10. The method according to claim 9, wherein said corresponding position information is generated upon a pressure on said touch sensitive membrane.

11. The method according to claim 8, wherein said retained data in said memory is processed in response to said selection.

12. The method according to claim 11, wherein one or more of said plurality of user interface elements correspond to a personal identification number.

13. The method according to claim 8, wherein each of said plurality of user interface elements correspond to one or more images formed on said surface of said card portion.

14. A computer-readable storage medium having a computer program recorded thereon, wherein the program is configured to map data retained in a memory of an electronic card with position information generated by a reading device configured to read said electronic card, said electronic card comprising a card portion having a plurality of user interface elements on a surface, wherein said retained data of said memory is associated with a corresponding one of user interface elements, wherein said memory is coupled to a processor means, and wherein a communication means couples said processor means to said reading device, said program comprising:

code for transmitting a selection of one of said user interface elements from said reading device to said processor means via said communication means;

code for associating said selection with said retained data using the processor means; and

code for using the association to perform a secure access checking function for enabling user access to a desired service,

wherein said selection is provided by a substantially transparent touch sensitive membrane of said reading device arranged to overlay said electronic card, wherein said membrane is responsive to pressure applied anywhere on the membrane, and wherein respective positions of the user interface elements are independent of predetermined positions on the membrane.

15. The program according to claim 14, further comprising code for generating an output signal according to said retained data based on the mapping.

16. The program according to claim 14, wherein said selection generates corresponding position information of said user interface element, and said memory and said processor means perform said mapping in order to associate said corresponding position information with said retained data to thereby interpret said selection.

17. The program according to claim 16, wherein said corresponding position information is generated upon a pressure on said touch sensitive membrane.

18. The program according to claim 14, wherein said retained data in said memory is processed in response to said selection.

19. The program according to claim 14, wherein one or more of said plurality of user interface elements correspond to a personal identification number.

20. The program according to claim 14, wherein said each of plurality of user interface elements correspond to one or more images formed on said surface of said card portion.
