Abstract: The disclosure is related to providing a payment processing service and a near field communication (NFC) tag processing service through the single smart card. The smart card may store identification (ID) information of one of a payment card and a NFC tag at a first memory sector and store associated information for providing a related service as the payment card and the NFC tag at predetermined memory sectors. The smart card may be also implemented with a NFC tag applet providing the ID information and the associated information as the NFC tag to the user terminal. The smart card may be recognized as the NFC tag while storing the ID information for the payment card at the first memory sector in the memory or as the payment card while storing the ID information for the NFC tag at the first memory sector in the memory.

Abstract: The disclosure is related to generating a temporal physical payment card with a predetermined valid period. One of virtual payment cards stored in user equipment is selected based on a selection input received from a user. Information on the selected virtual payment card is transferred to a physical dummy payment card with a predetermined valid period.

Abstract: Described embodiments provide a device for storing and managing a coupon in a smart card. Such a device may include a receiver, a sensor, a writer, and a reader. The receiver may be configured to receive at least one of a write request and a read request from a user where the read request is for reading a selected coupon from the smart card and the write request is for writing a selected coupon the smart card. The sensor may be configured to sense a near field communication (NFC) tag included in a smart card when the smart card is located within a predetermined distance from the device. The writer may be configured to store coupon data of a selected coupon in the smart card in response to the write request. The reader may be configured to read coupon data stored in the smart card in response to the read request. The smart card may be a combi card capable of radio frequency communication with other entities.

Abstract: Described embodiments provide a system and method for a global transit card service. The method may include receiving a global transit card service request from user equipment, where the global transit card service request includes information on a domestic transit card. The method may include transmitting information on an international transit card number for a target roaming area and information on a remaining balance in a foreign currency unit of the target roaming area to the user equipment. The information on the international transit card number of the target roaming area and the remaining balance in the foreign currency unit of the target area may be stored in an international transit card applet included in the user equipment.

Abstract: The disclosure is related to generating a temporal physical payment card with a predetermined valid period. One of virtual payment cards stored in user equipment is selected based on a selection input received from a user. Information on the selected virtual payment card is transferred to a physical dummy payment card with a predetermined valid period.

Abstract: The disclosure is related to sharing purchasing information among consumer using near field communication feature of user equipment. First user equipment may transfer purchasing information to second user equipment and the second user equipment may conveniently and instantly repurchase the same good or service, which the first user equipment purchases, based on the purchasing information.
