It has evolved to provide food.

In general, as a method of purchasing goods sold through a vending machine, when a buyer inputs coins or bills into a vending machine and selects a desired product, the selected item is discharged through an outlet. In addition, a vending machine is available to pay for goods using a credit card for buyers who do not have coins or bills.

Moreover, as the use of smartphones is becoming more common and the number of users of payment systems using smartphones increases, payment systems using smartphones have been introduced in vending devices.

An example of a payment system using a smartphone is a mobile payment system. Mobile payment systems have a simple advantage in their operating process, but they can only select items online, which can lead to confusion among customers, and buyers may be reluctant to use their location-based information on their smartphones. There is a problem.

As another example of a payment system using a smartphone, a payment method through an offline authentication module may be applied. Firstly, the use of OR optical cords has the advantage of being inexpensive and simple to configure, while causing the risk of damage due to external exposure, being inconvenient to use, and in which case a buyer will continue to occupy the vending machine There are disadvantages. Secondly, when using the NFC communication method, there is an advantage of providing a strong security, while there are disadvantages such as external exposure, inconvenience, expensive, the need for tagging (tagging) every option change. Third, in the case of using the Bluetooth communication method, the service is convenient and the service is automatically terminated when the buyer moves away from the vending device, while the security is weak.

The plurality of vending machines 100a and 100b, the user terminal device 300, the POS device 200, and the authentication server 400 may transmit and receive various information to each other through a predetermined network. However, here, only the flow of information used for authentication among the various information transmitted and received in the automatic sales system using the OTP is shown.

In addition, it will be described on the premise that the vending machine # 1 (100a) of the plurality of vending devices (100a, 100b) is selected by the user terminal device 300 to maintain the Bluetooth pairing.

When the vending machine # 1 100a and the user terminal 300 perform Bluetooth pairing, user information is transmitted from the user terminal device 300 to the vending machine # 1 100a.

In the present embodiment, the authentication server 400 corresponds to the case of performing authentication using OTP, the vending machine # 1 (100a), POS machine 200, the user terminal device 300, and the authentication server. It shows the flow of OTP between each other (400). At this time, the authentication information may include only OTP.

The OTP generated by the vending machine # 1 (100a) is transmitted to the POS machine 200 and the user terminal device (300). Thereafter, the POS device 200 transmits the received OTP to the authentication server 400, and the user terminal device 300 also transmits the received OTP to the authentication server 400.

By this operation, the authentication server 400 receives the OTP through the POS device 200 and the OTP through the user terminal 300, respectively, and performs authentication by comparing the two OTPs through these two paths. .

Thereafter, if the authentication is successful, the authentication server 400 transmits the OTP to the user terminal device 300, and the user terminal device 300 transmits the OTP to the vending machine # 1 100a again.

3 is a flowchart illustrating a flow of information used for authentication in an automatic sales system using OTP according to another embodiment of the present invention.

 As described in the previous embodiment, a variety of information is transmitted and received between the plurality of vending machines (100a, 100b), the user terminal device 300, the POS machine 200, the authentication server 400, but here used for authentication In order to explain in which path the information is transmitted, only the user information and the transmission path of the OTP are shown except for other information.

In the present embodiment, the authentication server 400 corresponds to a case where authentication is performed using user information, and describes a transmission path of user information and OTP. In this case, the authentication information may include OTP and user information.

Vending machine # 1 (100a) transmits the user information received from the user terminal device 300, and the OTP generated by itself to the POS machine 200. The POS machine 200 transmits the OTP and the user information received from the vending machine # 1 100a to the authentication server 400.

The user terminal device 300 also transmits its user information to the authentication server 400. As a result, the authentication server 400 retains the user information transmitted from the POS device 200 and the user information transmitted from the user terminal device 300. Therefore, the authentication server 400 may perform authentication by comparing user information.

If authentication using the user information is successful in the authentication server 400, the authentication server 400 transmits the OTP to the user terminal device 300, the user terminal device 300 sends this OTP again to the vending machine # 1 ( 100a). As a result, the vending machine # 1 100a may have an OTP received from the user terminal device 300 and an OTP generated by itself, and may perform authentication by comparing the two OTPs.

As a result, the OTP generated by the vending machine # 1 100a sequentially passes through the POS 200, the authentication server 400, and the user terminal 300, and then flows back into the vending machine # 1 100a. do. That is, the automatic vending machine # 1 (100a) determines that the authentication is successful only when the OTP generated by itself and the OTPs introduced through the devices in the system are matched, and the item is only recognized when the authentication is successful. Make it available.

The user operates the user terminal device 300 to search for a plurality of vending machines 100a and 100b in the sales place A to perform Bluetooth pairing (S603). In this case, the user may directly search by using the trade name of the sales place A entered by the user through a dedicated application of the user terminal device 300, or automatically search by using his own location information.

The user terminal device 300 may receive a selection signal for the vending machine # 1 100a to be used from the user through a dedicated application, and may also receive purchase information such as the type and number of items. (S605).

By Bluetooth pairing, the user terminal device 300 displays a list of a plurality of vending machines 100a and 100b that can be used in the sales place A, and the user holds the goods to be actually purchased through this list. One vending machine, that is, vending machine # 1 (100a) is selected. By this operation, the user terminal device 300 transmits a device selection signal to the selected vending machine # 1 (100a). In this case, the information transmitted together with the device selection signal transmitted from the user terminal device 300 to the vending machine # 1 100a includes user information and purchase information (S607).

The device selection signal transmitted from the user terminal device 300 is transmitted to the vending machine # 1 (100a), the vending machine # 1 (100a) generates an OTP (S609). At this time, the vending machine # 1 (100a) receiving the selection signal from the user terminal device 300 of the plurality of vending devices (100a, 100b) maintains the connection with the user terminal device 300, the predetermined communication maintenance The vending device that does not receive the selection signal within the time releases the connection with the user terminal device 300.

When the authentication information used for authentication in the authentication server 400 is set to be OTP, the vending machine # 1 100a may transmit the OTP to the user terminal device 300 (S610). This process may be omitted when the authentication information used for authentication in the authentication server 400 is user information.

Vending machine # 1 (100a) after generating the OTP, and transmits its own device information, and the OTP generated by the user with the user information obtained during the pairing process with the user terminal device 300 to the POS machine 200. (S611).

The POS machine 200 transmits the device information, the OTP, and the user information received from the vending machine # 1 (100a) and requests the authentication to the authentication server 400 (S613). In addition, the user terminal device 300 transmits user information and purchase information to the authentication server 400 to request authentication (S615).

(S616). This process may be omitted when the authentication information used for authentication in the authentication server 400 is user information.

When the authentication request of the POS device 200 and the authentication request of the user terminal device 300 are input, the authentication server 400 receives the OTP or user information received from the POS device 200 and the user terminal device 300. The authentication operation is performed using OTP or user information (S617).

After performing the authentication operation, the authentication server 400 transmits the authentication result together with the OTP received to the user terminal device 300 if the authentication is successful (S619). If the authentication operation is not successful in the authentication server 400, the subsequent step does not proceed.

After being notified that the authentication operation is normally performed by the authentication server 400, the user terminal device 300 transmits a purchase request signal together with the OTP received to the vending machine # 1 (100a) (S621).

When the OTP is transmitted from the user terminal device 300, the vending machine # 1 100a performs OTP authentication by comparing the received OTP with an OTP generated by itself (S623). More specifically, the vending machine # 1 (100a) determines that the authentication is successful when the OTP that is held and the OTP introduced from the outside match.

Vending machine # 1 (100a) notifies the authentication result to the user terminal device 300 in accordance with the OTP authentication (S625). In the present embodiment, it has been shown that the subsequent operation is performed on the premise that the OTP authentication of the vending machine # 1 100a succeeds. If the OTP authentication fails, the subsequent operation may not proceed any further.

After receiving notification that the authentication is successful from the vending machine # 1 (100a), the user terminal device 300 transmits user information and purchase information to the payment server 500 to request payment (S627).

The payment server 500 performs payment processing using the user information and the purchase information received from the user terminal device 300. In this case, since the user information includes credit card information of the user's name, and the purchase information includes the type and amount of goods to be purchased by the user, online payment is possible (S629).

The payment server 500 transmits the payment processing result to the authentication server 400 and the user terminal device 300 after the payment processing is performed (S631). In this case, when the payment process is not normally performed, the user terminal device 300 may be notified that the payment is not processed, and guide the user to use another payment means. The subsequent process will be described on the premise that the payment process has normally proceeded. If the payment process does not continue even if the user terminal device 300 continuously attempts to pay, the subsequent process may be terminated.

The user terminal 300 notifies the vending machine # 1 (100a) of the payment processing result received from the payment server 500 (S633), the vending device # 1 (100a) to the user terminal device (300). It provides the corresponding article that was selected by the (S635).

When the supply of the goods is completed, the vending machine # 1 100a transmits the purchase completion information to the user terminal 300, the authentication server 400, and the payment server 500 (S637). In addition, the purchase completion information is transmitted back to the POS device 200 from the authentication server 400 received the purchase completion information (S639).

Thereafter, the Bluetooth pairing between the vending machine # 1 100a and the user terminal 300 is released (S641).
