Abstract

A system and method for obtaining and storing information in an integrated circuit card is provided for use in a transaction over different environments. The card includes a memory unit having data records including formatted and unformatted fields, preferably comprising a name field, a data field and a security level field. The formatted fields are accessible, using generic labels and the unformatted fields are accessible using a non-generic label.

12. The memory device of claim 11, wherein the name portion of one of the plurality of formatted data records is used by one of the plurality of terminals to access the corresponding data portion of the one of the plurality of formatted data records.

13. The memory device of claim 11, wherein each of the plurality of formatted data records further includes a security level portion.

14. The memory device of claim 13, wherein the security level portion of each of the plurality of formatted data records is one of public, conditional and private.

15. The memory device of claim 14, wherein the data portion of one of the plurality of formatted data records may be read by one of the plurality of terminals if the security level portion of the one of the plurality of formatted data records is public.

16. The memory device of claim 14, wherein the data portion of one of the plurality of formatted data records may be read by one of the plurality of terminals having a particular decryption key if the security level portion of the one of the plurality of formatted data records is conditional based on the particular decryption key.

17. The memory device of claim 16, wherein the particular decryption key is an industry specific decryption key.

18. The memory device of claim 17, wherein the industry specific decryption key is specific to a card issuing authority.

19. The memory device of claim 18, wherein the card issuing authority is MasterCard.

20. The memory device of claim 18, wherein the data portion of one of the plurality of formatted data records may be read by one of the plurality of terminals if the security level portion of the one of the plurality of formatted data records is private only if a personal identification number is provided to the one of the plurality of terminals.

21. The memory device of claim 11, wherein a label stored in the non-generic name portion of one of the plurality of unformatted data records is known to one of the plurality of terminals that wrote the label.

22. The memory device of claim 21, wherein the one of the plurality of terminals transmits a message to another of the plurality of terminals, wherein the message contains a reference to the label stored in the non-generic name portion of the one of the plurality of unformatted data records.

23. The memory device of claim 11, wherein the terminal is one of a point of sale terminal, a personal computer, a personal digital assistant and a mobile device.

24. The memory device of claim 23, wherein the terminal can access data stored in the plurality of formatted data records if the terminal is a mobile device.

25. The memory device of claim 24, wherein the terminal can write data to the plurality of formatted data records if the terminal is a mobile device.

26. The memory device of claim 23, wherein the terminal can access data stored in the plurality of formatted data records and write data to the plurality of formatted data records if the terminal is a personal digital assistant.
