US 7,802,728 B2 · Microprocessor card defining a custom user interface

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).

Dependent claims

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.

5 more elements

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.
