In order to make the technical solution of the present disclosure clearer, each step of the self-checkout method will be described next.

In step S110, the user terminal interacts with the electronic price tag to obtain product information corresponding to the electronic price tag.

In this exemplary embodiment, a target shopping application can be installed on the user terminal. The target shopping application is a shopping APP for the current shopping place, that is, a third-party application of the user terminal. The target shopping application has a target control, and the target control Used to trigger interaction with electronic price tags. Shopping places can be large supermarkets, shopping malls, pharmacies, etc., or other shopping places, which are not limited in this example. The user terminal can be a mobile phone, a tablet, a wearable device, etc., which is not limited in this example.

In this exemplary embodiment, the electronic price tag, that is, the Electronic Shelf Label (ESL), is an electronic display device with information sending and receiving functions. It is placed on the shelf of a shopping place and can replace traditional paper Electronic display device for price tags. Each electronic shelf label communicates with the database server of the shopping place through a wired or wireless network to ensure that the product information corresponding to the electronic price tag on the shelf is the latest information. Electronic price tags can include display screens, NFC (Near Field Communication, Near Field Communication) sensing elements, price tag identification codes, etc. The display screen can display product name, price, unit, specifications, origin and other information, and can also include shelf time. , promotional information and other information related to the product, this example does not limit this. The product information can be the information displayed on the electronic price tag, such as product name, product number, product price, etc.

For example, in response to the first operation on the target control, the target interaction interface of the user terminal can be called to interact with the electronic price tag.

In this exemplary embodiment, the target control is an interactive control of the target interface of the user terminal, and the target interface refers to the shopping interface of the user terminal shopping application, such as the product purchase interface of the shopping place APP or the main interface of the shopping place APP, It can also be other interfaces of the shopping place APP, which is not limited in this example. The target interactive interface refers to the application program interface of the user terminal that can interact with the electronic price tag, for example, the near field communication reading interface (NFC reading interface) or the shooting interface of the user terminal camera, etc. The first operation may be the user's click, slide, hover, or other operations on the target control of the user terminal, or other interactive operations, which are not limited in this example.

For example, as shown in Figure 2, the electronic price tag includes an NFC sensing element (such as an NFC coil), and the user terminal includes a first NFC element and an NFC reading interface. The process of the user terminal interacting with the electronic price tag may include: Call the NFC reading interface to activate the first NFC element; interact with the NFC sensing element through the activated first NFC element. For example, the user clicks on the target control to call the NFC interface and activates it, and then brings the user's mobile phone close to the electronic price tag for NFC interaction.

Exemplarily, as shown in Figure 3, the electronic price tag includes a price tag identification code, and the user terminal includes a first shooting component (such as a mobile phone camera) and its shooting interface; the user terminal's interaction with the electronic price tag may include: calling the camera The shooting interface uses the first shooting component to shoot the price tag identification code for interaction. For example, the camera can scan the price tag identification code of the electronic price tag (such as the price tag QR code) to obtain the product information corresponding to the electronic price tag.

In step S120, the user terminal sends a shopping checkout request to the server based on the product information.

In this exemplary embodiment, the server is a backend server of the shopping place, used to manage product information in the shopping place. After the user's shopping is completed, for example, after the product purchase is completed, the user terminal can respond to the user's checkout operation and send a shopping checkout request to the backend server of the shopping place. The shopping checkout request can include product information to be checked out and user information (such as user information). Account, user level and other information). In some embodiments, users can also check out items to be checked out in stages. For example, if the user has multiple coupons, the user can check out the goods in stages, that is, send shopping checkout requests multiple times. In this example, users can freely check out the goods according to their needs. The checkout process is flexible and convenient, and the user experience is high.

In step S130, the server performs payment and settlement for the shopping behavior of the user terminal based on the received shopping checkout request, and generates a checkout voucher based on the checkout result; the checkout voucher is used for the server to verify the user's checkout situation when the user leaves the current shopping location.

In this exemplary implementation, the server can perform payment and settlement for the user's shopping behavior, and can treat each shopping checkout request as a shopping behavior. When the payment is successful, a checkout voucher for the current shopping behavior, such as a checkout QR code, is generated for the user. In some embodiments, the checkout voucher of the user terminal is scanned through the access control gate to obtain the corresponding bill identification information (such as a bill number); the bill identification information is sent to the server; the server generates the first access control instruction based on the received bill identification information ; and sends the first access control instruction to the access control gate; the access control gate controls its opening and closing state according to the first access control instruction. The first access control instruction is used to instruct the user whether to check out or whether to open the gate. When the user completes the checkout, open the gate to allow the user to leave the shopping place. For the situation where the user checks out in installments, the server can make a judgment and merge the multiple bills to form a corresponding checkout voucher.

In order to detect whether the checkout bill matches the shopping product, in some embodiments, the access control gate also includes a weight sensing element, and the method further includes: obtaining the weight information of the purchased product through the weight sensing element, and sending the weight information of the purchased product to the server ; The server determines the weight information of the checkout product based on the payment and checkout product information; compares the weight information of the purchased product with the weight information of the checkout product, generates a second access control instruction based on the comparison result, and sends the second access control instruction to the access control gate; Control the opening and closing status of the access control gate according to the second access control command.

In this example embodiment, the weight sensing element may be a weight sensor, and the weight information of the purchased goods refers to the actual weight information of the goods purchased by the user this time. The product information for payment and checkout refers to the theoretical weight of the product on the bill determined by the server based on the bill and the theoretical weight and quantity of the product in the bill. For example, the weight of the product can be determined by the net content recorded on the product. For example, when the user wants to leave the shopping place, the goods can be placed at the weighing position of the access control gate to weigh the goods, and at the same time, the bill identification (such as the bill number) is obtained by scanning the checkout voucher, and the bill identification and The actual weight of the product is sent to the server. The server will determine the theoretical weight of the billed product based on the bill identification, and then compare the theoretical weight of the product with the actual weight of the product. If the difference between the two is within the specified error range, it will generate a verified Second access control command, issue the second access control command to control the access control gate to be in the open state; if the difference between the two exceeds the specified error range, generate a second access control command that fails the verification, issue the second access control command to control the access control gate. The machine is off. When the verification fails, information such as the verification result and the reasons for failure can be delivered to the user terminal.

In some embodiments, the method further includes: in response to receiving an update message of the product information, the server determines the corresponding updated price tag information, and sends the updated price tag information to the corresponding electronic price tag through the gateway; the electronic price tag is based on the updated The price tag information is refreshed to display the updated price tag information.

In this example embodiment, the update message of product information may include updated product identification and corresponding update information, such as update content (product name, specifications, origin, etc.), update time, etc. Update price tag information refers to the information that needs to be updated on the electronic price tag, such as the electronic price tag display information. In this example, the managers of the shopping mall can maintain and update the products in the server. For example, they can update the product information through the operation and maintenance terminal and generate an update message for the product information. The server and the electronic price tag communicate through the gateway. The gateway encodes the updated price tag information transmitted by the server and sends it to the electronic price tag. The electronic price tag is decoded and displayed.

In some embodiments, the method further includes: binding the electronic price tag and the corresponding product to a corresponding relationship through the second near field communication component or the second photographing component of the handheld device, and uploading the binding relationship to the server.

In this example implementation, the corresponding relationship between the electronic price tag and the corresponding product information can be bound through a handheld device (such as a personal digital assistant, PDA). The handheld device is a device used by workers for shelf management and electronic price tag information maintenance; specifically, the electronic price tag can be scanned through the second near field communication element (NFC element) or the second photographing component (camera) of the handheld device. The NFC coil or price tag identification code binds the electronic price tag to the corresponding product information, and the server is used to store the binding relationship of all electronic price tags corresponding to the product information.

Referring to Figure 4, a self-checkout method in another embodiment provided by the present disclosure may include the following steps:

Step S401: The customer opens the target interface (such as the shopping cart interface) of the corresponding shopping APP on the user terminal. For the first operation of the target control, the target interactive interface of the user terminal is called to interact with the electronic price tag to obtain the corresponding product information. .

In this example, the target control can be the add product control. You can choose to add products by NFC or add products by scanning QR code according to the prompts. NFC method: Put the NFC of the mobile phone to the NFC of the electronic price tag to read the information. The product information will pop up. After selecting the purchase quantity, the product is added to the APP shopping cart. Code scanning method: The APP calls the mobile phone camera shooting application interface, pops up the camera shooting interface, uses the mobile phone camera to scan the price tag identification code on the electronic price tag to read the information, pops up product information, selects the purchase quantity, and adds the product to the APP for shopping In the car. You can add or delete items in the APP shopping cart.

Step S402: The customer performs a payment operation on the shopping cart interface of the user terminal, and the user terminal generates a shopping checkout request based on the product information.

Step S403: The user terminal sends a shopping checkout request to the server.

Step S404: The server performs payment and settlement on the shopping behavior of the user terminal, and generates a settlement voucher based on the settlement result.

Step S405: The server sends the checkout voucher to the user terminal.

Step S406: The user terminal scans the checkout voucher at the access control gate so that the access control gate obtains the bill identification.

Step S407: The access control gate weighs the actual weight of the goods purchased by the user.

Step S408: The access control gate sends the actual weight and bill identification of the purchased goods to the server.

Step S409: The server determines the theoretical weight corresponding to the billed product based on the bill identification, compares the actual weight of the purchased product with the theoretical weight of the billed product, and generates an access control instruction based on the comparison result.

Step S410: The server sends the access control instruction to the access control gate, so that the access control gate controls the opening and closing state of the access control gate according to the access control instruction.

In the above embodiment, the electronic price tag and corresponding product information have been pre-bound and maintained in the server.
