determining, by the server computer, a set of tax rules that apply to the determined tax jurisdiction associated with the transaction,

determining, by the server computer, a tax amount based on the transaction amount and the determined set of tax rules,

determining, by the server computer, a total transaction amount based on the tax amount and the transaction amount, and

converting, by the server computer, the total transaction amount to a currency based on a conversion rate, wherein the conversion rate is based on the location of the mobile communication device, a location related to an account of the consumer and the time of the transaction;

receiving, by the mobile communication device or the access device, the converted total transaction amount and the tax amount; and

displaying, by the mobile communication device or the access device, the received total transaction amount and the tax amount on a display.

determine a set of tax rules that apply to the determined tax jurisdiction associated with the transaction,

determine a tax amount based on the transaction amount and the determined set of tax rules,

determine a total transaction amount based on the tax amount and the transaction amount, and

convert the total transaction amount to a currency based on a conversion rate, wherein the conversion rate is based on the location of the mobile communication device,

location related to an account of the consumer and the time of the transaction;

code for receiving the converted total transaction amount and the tax amount;

code for displaying the received total transaction amount and the tax amount on a display; and

a processor in communication with the computer readable medium.

determining, by a server computer, a location of a mobile communication device operated by the consumer;

determining, by the server computer, a tax jurisdiction based on the location of the mobile communication device;

determining, by the server computer, a set of tax rules that apply to the determined tax jurisdiction associated with the transaction;

determining, by the server computer, a tax amount based on the transaction amount and the determined set of tax rules;

determining, by the server computer, a total transaction amount based on the tax amount and the transaction amount;

converting the total transaction amount to a currency based on a conversion rate, wherein the conversion rate is based on the location of the mobile communication device, a location related to an account of the consumer and the time of the transaction; and

sending the converted total transaction amount and the tax amount.

11. The method of claim 10 , further comprising converting the tax amount to the currency based on the conversion rate based on the location of the mobile communication device.

12. The method of claim 10 , wherein the converted total transaction amount or the tax amount is sent to the access device.

13. The method of claim 10 , wherein the converted total transaction amount or the tax amount is sent to the mobile communication device.

14. The method of claim 10 , further comprising sending the conversion rate to the mobile communication device.

15. The method of claim 10 , wherein the location of the mobile communication device is determined based on GPS data from the mobile communication device.

16. The method of claim 1 , wherein the server computer is further configured to determine the location of the merchant based on a signal strength and a location of a nearest cell tower.

17. The method of claim 10 , wherein the location of the mobile communication device is determined based on a signal strength and a location of a nearest cell tower.

18. The method of claim 1 , wherein an issuer that opens and maintains an account associated with the consumer provides the conversion rate to the server computer.

19. The method of claim 8 , wherein the secure coupon is based on the location of the mobile communication device.

20. The method of claim 8 , wherein the secure coupon is associated with one or more items in the transaction.
