    Abstract: Various embodiments of the present invention relate to an access control method for a smart card and an electronic device using the same, the method comprising the steps in which: a processor refreshes the smart card to update identification information when the electronic device is located in a predetermined region; the processor stores, in a memory, information before the identification information is updated; the processor stores the updated identification information in smart card information of the smart card; the processor checks whether identification information before the update is stored in the memory when the updated identification information is included in blacklist information of the memory; the processor determines whether the identification information before the update is included in the blacklist information; and the processor allows an access to the smart card, when the identification information before the update is not included in the blacklist information, such that a user normally buying and using an electronic device at a specific region could not have a limitation related to regional locking, caused by refreshing of identification information of the smart card, which can occur while visiting a country on a blacklist. Other various embodiments are possible.
