A payment service device for a vending machine that enables payment processing for products of a vending machine through a vending machine and discharges a purchased product from the vending machine upon completion of the payment processing, and a vending machine service system including the same.

In general, a vending machine has a cash slot for payment, and with the recent development of smartphones and payment systems, it communicates with the user's smartphone through short-distance wireless communication to obtain payment method information and then recognizes a card that can process payment An add-on is configured in a vending machine.

For example, the card recognition unit of the vending machine acquires payment method related information stored in the smart phone through near field communication (NFC) with the smart phone and processes the payment, even if the user does not have cash. We support the purchase of products stored in .

However, in the case of a smartphone that does not support the NFC method, there is a problem that the vending machine cannot be used, and the use process is cumbersome because the mobile card for payment must be registered in the smartphone and then linked with the NFC method.

In place of the NFC-based payment, which has such a problem, a method in which a card recognition unit that communicates based on Bluetooth is configured in the vending machine, communicates with the user's smartphone through Bluetooth to obtain payment method information, and then processes the payment have.

Since this Bluetooth-based short-distance wireless communication is supported by most smartphones, there is an advantage in overcoming the limitations of the existing NFC method.

However, in the case of a conventional vending machine having a card recognition unit using Bluetooth, if a user leaves the vending machine while the card recognition unit communicates with a smartphone through pairing, the card is recognized while the session created through pairing is maintained as it is. The add-on continuously searches for the user's smartphone, and as a result, if the user deviates from the location of the vending machine because the user does not intend to use the vending machine, communication is connected to the card recognition unit to the other user's smartphone in order for other users to use the vending machine There is a problem that a connection cannot be established even if you try to do so, and there is a problem that you have to wait until the corresponding communication session is terminated.

Accordingly, although the communication connection failure between the card recognition unit and other users' smartphones due to maintaining the existing communication session is not due to the failure of the vending machine, other users recognize this communication connection failure as a failure of the vending machine. It is reported to the vending machine manager, and there is a problem in that unnecessary failure reports occur frequently.

In addition, in the case of a vending machine equipped with a Bluetooth-based card recognition unit, when there are a plurality of vending machines equipped with a card recognition unit supporting Bluetooth-based payment processing and the plurality of vending machines are adjacent to each other, a user who wants to use a specific vending machine among the plurality of vending machines There is a case that the Bluetooth signal transmitted from the smartphone is received not only from the specific vending machine but also from the other vending machine. Since the payment process can be performed with the Bluetooth signal transmitted from the smartphone, payment errors frequently occur during the payment process, and there is a problem that the user cannot properly use the vending machine.

In addition, in the existing vending machines having a Bluetooth-based card recognition unit, when a plurality of different users' smartphones are adjacent to one vending machine, each of the plurality of users' smartphones receives the Bluetooth signal transmitted by the card recognition unit of the vending machine. There may also be cases where a response may occur, which causes a problem in that it is difficult for the card recognition unit of the vending machine to specify the user currently using the vending machine.

In addition, there may be a problem in that an intruder with malicious intent to interfere with the operation of the vending machine attempts a Bluetooth connection to the vending machine while the normal user is using the vending machine using his/her smartphone, thereby interfering with the user's use of the vending machine. has a difficult problem in preventing such malicious interference.

In this case, the application unit 210 may transmit the Bluetooth signal to the payment service device 100 through the short-range wireless communication module 240 without Bluetooth-based pairing when the magnetic force is greater than or equal to a preset reference value.

In addition, the terminal control unit of the user terminal 200 may be automatically activated as the application unit 210 by executing the application when the magnetic force strength according to the measurement information is equal to or greater than a preset reference value.

Meanwhile, the control unit 130 of the payment service device 100 may receive a Bluetooth signal transmitted from the user terminal 200 through the short-range wireless communication unit 120 configured in the payment service device 100 .

At this time, the control unit 130 of the payment service device 100 also uses a Bluetooth-based short message transmission method without pairing with the user terminal 200 through the short-range wireless communication unit 120 with the user terminal 200 and a preset protocol. You can send and receive messages according to

Here, the protocol may be set in the control unit 130 .

Accordingly, the payment service device 100 and the application unit 210 of the user terminal 200 may identify each other by communicating with each other in a Bluetooth-based short message transmission method according to the preset protocol.

For example, the application unit 210 generates an identification request message including terminal identification information of the user terminal 200 configured with the application unit 210 according to a preset protocol when the magnetic force greater than or equal to the reference value is detected, and the Through the short-range wireless communication module 240 of the user terminal 200, a Bluetooth signal may be transmitted to the payment service device 100 without pairing (S2).

In this case, the terminal identification information includes a variety of information that can identify the user terminal 200, such as a MAC address (Media Access Control Address) of the user terminal 200, MDN (Mobile Directory Number) of the user terminal 200, etc. can do.

In addition, the short-range wireless communication unit 120 of the payment service device 100 transmits an identification request message for identifying the user terminal 200 received from the user terminal 200 as a Bluetooth signal to the user terminal 200 . It is received without pairing with the payment service device 100 and provided to the controller 130 of the payment service device 100 .

At this time, since the short-range wireless communication unit 120 of the payment service device 100 receives a Bluetooth signal in a short message transmission/reception method without pairing, it receives a Bluetooth signal from various terminals in addition to the Bluetooth signal of the user terminal 200, and the corresponding Bluetooth signal is received. The message included in the signal is transmitted to the control unit 130 of the payment service device 100 .

Accordingly, the control unit 130 may measure the radio wave strength for each one or more Bluetooth signals received by the short-range wireless communication unit 120 in conjunction with the short-range wireless communication unit 120, and the radio wave strength among the one or more Bluetooth signals is Only messages included in the largest specific Bluetooth signal can be received.

Through this, since the user terminal 200 in contact with the magnet unit 110 is closest to the vending machine in which the payment service apparatus 100 is configured, the control unit 130 of the payment service apparatus 100 controls the user terminal 200 ) can accurately distinguish a Bluetooth signal including a message transmitted from other Bluetooth signals.

In addition, the control unit 130 blocks the remaining Bluetooth signals except for the Bluetooth signal transmitted by the user terminal 200 and having the greatest radio wave strength, so as to perform pairing between the payment service device 100 and the user terminal 200 . It is possible to control the payment service device 100 to communicate only with the user terminal 200 without it.

In addition, the control unit 130 of the payment service device 100 includes device identification information of the payment service device 100 in response to the identification request message when the user terminal 200 is identified according to the identification request message. A response message may be generated and transmitted to the user terminal 200 (S3).

In this case, the application unit 210 of the user terminal 200 also receives another message from another device or terminal in addition to the payment service device 100 through the short-range wireless communication module 240 during communication with the payment service device 100 . It can receive Bluetooth signals from devices or other terminals.

Accordingly, the application unit 210 of the user terminal 200 also interworks with the short-range wireless communication module 240 during communication with the payment service device 100 like the control unit 130 of the payment service device 100 . Thus, only the message included in the Bluetooth signal having the greatest radio wave strength among the Bluetooth signals received by the short-range wireless communication module 240 is received and transmitted from the payment service device 100 of the vending machine closest to the user terminal 200 message can be accurately identified.

In addition, the application unit 210 of the user terminal 200 blocks the remaining Bluetooth signals except for the Bluetooth signal having the greatest radio wave strength among the Bluetooth signals received through the short-range wireless communication module 240, so that the vending machine is not paired. The user terminal 200 may be controlled to communicate only with the payment service device 100 of

In particular, even when a type vending machine is disposed adjacent to a specific vending machine being used by the user and the payment service device 100 is also configured in the type vending machine, the user's user terminal 200 is more connected to the specific vending machine than the type vending machine. Since the radio wave strength of the Bluetooth signal received from the payment service device 100 of the specific vending machine is the greatest and is received by the user terminal 200 closer, the application unit 210 of the user terminal 200 allows the user to The vending machine in use can be easily specified as the specific vending machine in which the radio wave strength of the Bluetooth signal is measured the greatest.

Through the above-described configuration, the payment service device 100 and the user terminal 200 can accurately identify and identify each other through a Bluetooth-based short message transmission method without mutual pairing.

On the other hand, when confirmation of a communication target is completed based on a message according to a protocol preset between the payment service device 100 and the application unit 210 of the user terminal 200, the application unit of the user terminal 200 210 may check the storage unit 270 according to the preset protocol to determine whether payment method information for the user's payment method is stored in the storage unit 270 ( S4 ).

In this case, the payment method information may include at least one of mobile payment card related information and point information stored in the user terminal 200 .

In addition, when payment method information is confirmed, the application unit 210 transmits a Bluetooth signal including a specific message according to a preset protocol for confirmation completion of the payment method information through the short-range wireless communication module 240 to the payment service It can be transmitted to the device 100 (S5).

For example, the application unit 210 of the user terminal 200 checks payment method information in the storage unit 270 when receiving a response message in response to the identification request message, and when the payment method information is confirmed (existence) If) a specific message including device identification information and terminal identification information extracted from the response message, and including confirmation completion information on completion of confirmation of the payment method information, is generated, and then a Bluetooth signal is transmitted through the short-range wireless communication module 240 to transmit the specific message to the payment service device 100 .

In the above configuration, when the payment method information is a point, the application unit 210 may communicate with a preset external server that issues the point through a communication network through the communication module 250, and when the response message is received, the After transmitting point confirmation request information about the user's accumulated points issued and stored to the user to an external server, and receiving the holding point status information from the external server in response to the point confirmation request information, the holding point status information is based on the If the user's holding points exist, the specific message may be generated and transmitted to the payment service device 100 .

In addition, in the above-described configuration, the application unit 210 does not check the payment method information corresponding to the user in the external server or the storage unit 270 because there is no holding point for the user or a payment card is not registered.
