7. The portable electronic device of claim 1 , wherein the instructions are further configured to cause the portable electronic device to:

obtain configuration information including at least one security policy to be applied at a time of payment corresponding to the second country in response to reception of a user's selection after displaying the guidance for payment in the second country.

8. The portable electronic device of claim 1 , wherein the instructions are further configured to cause the portable electronic device to identify that the country in which the portable electronic device is located is changed based on at least one of a mobile country code (MCC), a mobile network code (MNC), or global positioning system (GPS) location information.

9. A method for supporting mobile payment in a portable electronic device, the method comprising:

identifying that a country in which the portable electronic device is located is changed;

if the country in which the portable electronic device is located is changed from a first country to a second country, displaying information on an available form of payment for the second country;

displaying a guidance for the available form of payment in the second country based on payment-related configuration information while a payment application is executed;

selecting a form of payment by a user input;

in response to the selection, changing a first authentication method for the first country to a second authentication method for the second country; and

performing, using the payment application stored in a memory of the portable electronic device, payment using one of a plurality of tokens pre-stored in the memory based on the second authentication method with the selected form,

wherein the first authentication method is associated with information on the first country that includes a one-time payment token, and

wherein the second authentication method is associated with information on the second country that includes using a the plurality of tokens, and

wherein the guidance includes information that an overseas payment is required.

10. The method of claim 9 ,

wherein the first authentication method is a method in which a payment token required to perform payment is issued from an external server at every payment, and

wherein the second authentication method is a method in which any one of a plurality of pre-stored payment tokens is used.

11. The method of claim 9 , wherein the changing of the first authentication method to the second authentication method corresponding to the information on the second country comprises:

obtaining configuration information including at least one security policy to be applied at a time of payment corresponding to the second country; and

changing to the second authentication method based on the configuration information.

12. The method of claim 11 , wherein the at least one security policy includes at least one of a security policy supported by the portable electronic device itself, a security policy for each country supporting overseas payment, a security policy for each form of payment supporting overseas payment, a security policy according to a payment method, or a security policy according to a payment amount.

13. The method of claim 10 , further comprising:

issuing a device nonce for authentication on the plurality of pre-stored payment tokens according to a request to execute the payment application and transmitting the device nonce to a payment server connected to a financial server to perform authentication between the financial server and an authentication server; and

completing authentication of the plurality of pre-stored payment tokens by receiving a verification result for the device nonce from the payment server.

14. The method of claim 13 , wherein the transmitting of the device nonce to the payment server comprises:

requesting authentication on biometric information from the authentication server according to the request to execute the payment application; and

transmitting the device nonce to the payment server when the authentication on the biometric information by the authentication server is successful.

15. The method of claim 9 , further comprising:

obtaining configuration information including at least one security policy to be applied at a time of payment corresponding to the second country in response to reception of a user's selection after displaying the guidance for payment in the second country.
