Abstract

Processing an access transaction involves receiving application data from a portable consumer device at an agency reader for use in connection with a transaction, the application data having a predetermined data field configuration for processing the transaction by an issuer of the portable consumer device, and accessing at least one data file of the portable consumer device at the agency reader, wherein the configuration of the data file is determined by the issuer and stores agency data associated with use of the portable consumer device for the transaction.

Claims

1. A portable consumer device comprising:

application data for use in connection with transactions, the data having a predetermined data field configuration for use with a reader of an agency for processing a transaction that involves the portable consumer device;

at least one data file, wherein the configuration of the data file is determined by the issuer of the portable consumer device for use by the agency.

2. The portable consumer device of claim 1, wherein the data file configuration relates to data capacity of the data file, location of the data file of the portable consumer device, and encryption keys needed to gain access to the data file.

3. The portable consumer device of claim 1, wherein the agency can write to and read from the data file in accordance with encryption keys that are determined by a portable consumer device issuer.

4. The portable consumer device of claim 3, wherein the agency can determine if the encryption keys do not function to provide access to the data file and can thereby determine that the portable consumer device is likely fraudulent.

5. The portable consumer device of claim 3, wherein the predetermined data field configuration utilizes encryption keys that are provided to agencies to gain access to the data files.

6. The portable consumer device of claim 5, wherein access to a particular data file is further controlled by an agency to whom the particular data file has been assigned by the issuer.

7. The portable consumer device of claim 1, wherein one of the data files comprises blocking data that can be set to a blocked status, such that the agency will halt transaction processing upon determining that the blocking data has a blocked status.

8. The portable consumer device of claim 7, wherein the agency sets the blocking data to the blocked status upon checking a negative list of unauthorized portable consumer devices and determining that the portable consumer device is on the negative list.

9. The portable consumer device of claim 8, wherein the agency deletes the portable consumer device from the negative list after setting the blocking data to the blocked status.

10. The portable consumer device of claim 1, wherein the portable consumer device includes a plurality of issuer assigned data files, and wherein each of the issuer assigned data files is configured to receive and store data files from an agency in accordance with a different data file specification for each data file so as to be accessible to a predetermined agency and to no other agencies.

11. The portable consumer device of claim 10, wherein one or more of the issuer assigned data files contain data for calculation of agency charges associated with use of the portable consumer device.

12. The portable consumer device of claim 11, wherein the agency comprises a transit agency and the agency charges comprise transit charges.

13. The portable consumer device of claim 1, wherein the portable consumer device comprises a contactless smart card device.

14. A method of processing an access transaction, the processing method comprising:

receiving application data from a portable consumer device at an agency reader for use in connection with a transaction, the application data having a predetermined data field configuration for processing a transaction that involves the portable consumer device;

accessing at least one data file of the portable consumer device at the agency reader, wherein the configuration of the data file is determined by the issuer and stores agency data associated with use of the portable consumer device for the transaction.

15. The method of claim 14, wherein accessing at the agency reader comprises writing to and reading from the data file in accordance with encryption keys that are determined by the issuer.

16. The method of claim 15, wherein accessing at the agency reader further comprises determining if the encryption keys do not function to provide access to the data file and thereby determining that the portable consumer device is likely fraudulent.

17. The method of claim 15, wherein the predetermined data field configuration utilizes encryption keys that are provided to agencies share access to the data files.

18. The method of claim 17, wherein access to a particular data file is further controlled by an agency to whom the particular data file has been assigned by the issuer.

19. The method of claim 17, wherein the data file configuration relates to data capacity of the data file, location of the data file of the portable consumer device, and encryption keys needed to gain access to the data file.

20. The method of claim 14, wherein one of the data files comprises blocking data that can be set to a blocked status, such that the agency will halt transaction processing upon determining that the blocking data has a blocked status.

21. The method of claim 20, wherein the agency sets the blocking data to the blocked status upon checking a negative list of unauthorized portable consumer devices and determining that the portable consumer device is on the negative list.

22. The method of claim 21, wherein the agency deletes the portable consumer device from the negative list after setting the blocking data to the blocked status.

23. The method of claim 14, wherein the portable consumer device includes a plurality of issuer assigned data files, and wherein each of the issuer assigned data files is configured to receive and store data files from an agency in accordance with a different data file specification for each data file so as to be accessible to a predetermined agency and to no other agencies.

24. The method of claim 23, wherein one or more of the issuer assigned data files contain data for calculation of agency charges associated with use of the portable consumer device.

25. The method of claim 24, wherein the agency comprises a transit agency and the agency charges comprise transit charges.

26. The method of claim 14, wherein receiving application data comprises reading from a portable consumer device comprising a contactless smart card device.
