It is widely used as a contactless wireless communication module using a frequency band.

In addition, since the NFC communication module 117 transmits data at a close distance of about 10 cm, as illustrated in FIG. 3, the NFC communication module 117 may include a Bluetooth module 118 and a wireless Internet module 113. Has a shorter short-range communication range than

Meanwhile, in the mobile terminal 100 according to the present invention, for example, as illustrated in FIG. 4, an NFC tag is provided using the NFC communication module 117 which is one of the short range communication modules. Various item information about items 500 ₁ to 500 _k is obtained. The item information may include an item price, a manufacturer, a feature point, and the like.

In addition, the controller 180 of the mobile terminal displays the item information obtained as described above through the display unit 151 and also allows the user to make a virtual payment primarily. ) Displays at least one payment method (eg, credit card) that is stored and managed.

In addition, when the user selects any one payment method or automatically selects the payment method having the highest discount rate, the controller 180 stores and manages the item information and payment means as virtual payment information. The virtual payment information may include various pieces of information for allowing a predetermined payment amount to be divided into a plurality of payment means.

In addition, in the controller 180, after the user decides to purchase an item, as shown in FIG. 5, when the mobile terminal 100 approaches the checkout terminal 600, the control unit 180 includes an NFC module included in the checkout terminal. By performing communication, the final payment is performed. In this case, the final payment is divided into a plurality of payment means based on the virtual payment information.

6 is a flowchart illustrating an embodiment of a method for controlling a mobile terminal according to the present invention. When the user approaches the mobile terminal 100 to an item to be purchased, the NFC communication module of the mobile terminal ( 117 reads the NFC tag information in the article, and acquires various purchased article information such as a price, a manufacturer, and a feature point of the purchased article (S10).

The predetermined payment amount for the purchased article is divided into a plurality of payment means for virtual payment (S11). For example, as shown in FIG. 7, the mobile terminal 100 is attached to the first article. Upon accessing to obtain price information about the first article, the controller 180 of the mobile terminal displays at least one payment means stored in the storage 160 through the display unit 151. .

For example, the display unit 151 may include an A card that can receive a discount when a predetermined monthly payment amount is achieved, a B card that can receive a discount for a specific item or a merchant, and a specific time period. You will be presented with a list of C cards that are eligible for the discount.

On the other hand, in the controller 180, when the user selects the A card as a payment means for the price 50,000 won of the first article, the virtual payment of 50,000 won of the first article with the A card, and then the user, If B card is selected as a payment method for the price of 100,000 won of the second item, the virtual card will be settled for 100,000 won of the second item with the B card. If the discount rate of the B card is 5%, the second item The estimated amount of payment is 95,000 won, so the total amount of virtual payments is 145,000 won.

And, when the user approaches the mobile terminal 100 to the cashier terminal 600 for the final payment, the NFC communication module 117 of the mobile terminal, NFC with the NFC module of the cashier terminal 600 After the communication is established and the calculation link is established (S12), based on the virtual payment, the final payment for the total payment of 145,000 won is made by dividing 50,000 won into A card and 95,000 won into B card (S13).

Accordingly, the payment amount for the various items to be purchased by the user can be divided into a plurality of payment means for payment.

On the other hand, as another embodiment according to the present invention, the price of one item may be divided into a plurality of payment means, for example, as shown in Figure 8, the price of the second article is 100,000 won, The user can select the A card to make a virtual payment of 50,000 won, and select the B card to make a virtual payment of 50,000 won, whereby a message indicating the achievement of the monthly payment amount of the A card and the 5% discount rate of the B card A message indicating the application may be displayed.

In addition, by applying the 5% discount rate of the B card, a 50,000 won is an A card, 47,500 won is a B card, a message indicating that the total amount of the virtual payment is 97,500 won may be displayed, after which the user, for the final payment When the mobile terminal 100 approaches the checkout terminal 600, the final payment is 97,5000 won based on the virtual payment. The 50,000 won is divided into the A card and the 47,500 won is the B card.

Accordingly, the payment amount for one item to be purchased by the user can be divided into a plurality of payment means for payment.

FIG. 9 illustrates a process in which a mobile terminal according to an embodiment of the present invention acquires virtual payment information of another mobile terminal through NFC communication, and FIG. 10 illustrates another method for controlling a mobile terminal according to the present invention.

In operation 100, a predetermined partial amount of money is virtually settled by any one payment means selected by the first user (S20).

In the second terminal 200, the virtual payment information is virtually settled by a predetermined payment method selected by the second user, and then the virtual payment information is selected by the user. 100).

For example, as illustrated in FIG. 11, the first user may make a virtual payment of 6,000 won using an A card using the first mobile terminal 100, and the second user may use a second mobile terminal ( 20), you can virtually pay 6,000 won with B card.

And, the second user, the virtual payment information specifying that the 6,000 won payment with the B card in the state in which the second mobile terminal 200 approaches the first mobile terminal 100, through NFC communication The first mobile terminal 100 may be transmitted to the first mobile terminal 100.

Meanwhile, as shown in FIG. 11, the first mobile terminal 100 confirms whether the first user approves whether to accept the virtual payment authority of the other person received from the second mobile terminal 200. If approved, the virtual payment information of the first user and the virtual payment information of the second user are respectively displayed.

For example, the first mobile terminal may display a message indicating that the total amount is 120,000 won along with a message about A card 6,000 won as virtual payment information and B card 6,000 won as virtual payment information of another person. have.

And, when the user approaches the first mobile terminal 100 to the cashier terminal 600 for the final payment, the NFC communication module 117 of the first mobile terminal 100, the cashier terminal 600 After performing the NFC communication with the NFC module, and establishes the calculation link (S22), based on the virtual payment, A card 6,000 won, B card 6,000 won to make a final payment of a total of 12,000 won (S33).

Accordingly, the total cost jointly used by several users is paid by one user using a mobile terminal, but each user can appropriately divide a portion of the total cost.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and changes can be made without departing from the spirit and scope of the present invention.
