[0002] In today's business transaction environment, with the rapid development of electronic payment and information management, the Point of Sale (POS) has become an indispensable tool in the retail and service industries, widely used for processing customer payment transactions. As a key interaction interface between merchants and customers, the POS terminal can not only complete payment functions, but also provide multiple functions such as price verification, promotion application, and inventory update.

[0003] In the transaction process, each transaction is assigned an order number. This order number is not only an identifier for the transaction, but also plays a crucial role in subsequent transaction queries, reconciliation, after-sales processing, inventory management, and financial audits. Whether it is when a customer returns or exchanges goods, or when a merchant reconciles accounts, the order number is the core element to ensure accurate transaction identification and traceability. Traditional POS terminals usually rely on the order number manually input by the merchant to complete the payment operation.

[0004] However, with the rapid development of e-commerce and the explosion of the order volume, the format and length of the order number have become increasingly complex and lengthy, which not only increases the difficulty of manual input, but also is prone to errors, affecting the efficiency and accuracy of transactions.

[0042] The present disclosure will be further described in detail below with reference to the accompanying drawings and examples. It can be understood that the specific examples described herein are only for explaining the relevant content and do not limit the present disclosure. Additionally, it should be noted that for the sake of description, only parts related to the present disclosure are shown in the drawings.

[0043] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0044] Taking a large-scale comprehensive supermarket with high customer flow as an example, after a customer selects goods and goes to the cashier area to check out. After the customer scans the goods in the cashier area, the system generates a complex order number such as "20231105SF081520XYZQ" based on multi-dimensional information such as the current date, time, store number, and serial number; among them, 20231105 is the date of the day, SF represents the fresh food area, 081520 is the serial number, and the last XYZQ is the code used to distinguish different batches. When the user chooses to pay using the POS terminal, they need to manually enter the order number on the POS terminal to search for the order, confirm the payment, and write off the inventory. For an order number like "20231105SF081520XYZQ", which is a mixture of numbers and letters, it is very easy to enter the wrong numbers or confuse numbers and letters during the busy peak hours, and once entered incorrectly, it is necessary to operate again, greatly reducing the efficiency and accuracy of the transaction.

[0045] Figure 1 Shows an application scenario of a POS terminal payment method according to an embodiment of the present disclosure. In this application scenario, it may include a user terminal 100, a server 200, and a POS terminal 300. The user terminal 100 and the POS terminal 300 are respectively connected to the server 200 through a network. The user terminal 100 may be equipped with a scanning device (such as a two-dimensional code scanner, a bar code scanner, etc.) for scanning codes, uploading a settlement request, receiving, and displaying a simplified number; the server 200 is used to generate an order number according to the settlement request and obtain the simplified number and then send it to the user terminal 100; the POS terminal 300 is used to send the simplified number input by the user to the server 200; the server 200 is also used to obtain the order information according to the simplified number sent by the POS terminal 300 and then return it to the POS terminal 300, so that the POS terminal 300 displays the order information for the user to complete the payment when the information is verified to be correct.

[0046] For ease of description and to make the technical solutions of the specific embodiments of the present disclosure easier to understand, before describing the POS terminal payment method implemented in the present disclosure, the technical terms involved in the specific embodiments of the present disclosure are explained as follows: The POS (Point of Sale) terminal is used to assist merchants in completing many important tasks such as commodity sales, payment settlement, membership management, and transaction data management. It is a key tool for realizing the digitization and convenience of offline transactions.

[0047] Order information refers to the data and details related to a transaction.

[0048] Figure 2 The overall flowchart of the POS terminal payment method M100 according to an embodiment of the present disclosure is shown. As Figure 2 shown, the POS terminal payment method includes steps S110 to S130. Among them, the POS terminal payment method can be executed by an electronic device such as a POS terminal.

[0049] Specifically, Figure 2 the shown POS terminal payment method includes: Step S110, providing an order query interface.

[0050] In some embodiments of the present disclosure, the order query interface provided by step S110 is an interface that allows users to query target orders; its main function is to enable users to accurately locate the order to be queried according to the query conditions. The order query interface can be the main interface or a sub-interface of the main interface.

[0051] Figure 3 is a schematic diagram of an order query interface according to an embodiment of the present disclosure. The order query interface realizes order query through a search box and a query control. When querying an order, the user can enter a search term in the search box and click the query control to realize order query.

[0052] Step S120, in response to the received order query instruction of the order to be queried input by the user based on the order query interface, providing an order payment interface.

[0053] In some embodiments of the present disclosure, the order query instruction in step S120 carries a simplified number of the order number of the order to be queried input by the user. The simplified number is used as a query condition to obtain the order information of the order to be queried from the server for the user to check; the order payment interface displays at least one payment control and the order information of the order to be queried.

[0054] For Figure 3Taking the order query interface shown as an example, when the user enters a simplified number in the search box and clicks the query control, the POS terminal can receive the order query instruction of the order to be queried input by the user based on the order query interface.

[0055] At least one payment control displayed on the order payment interface is used to interact with the payment system to help the user complete the payment process; different payment controls support different payment methods. In step S120, at least one payment control may include one or more of a card swiping payment control, a code scanning payment control, a cash payment control, and an NFC payment control.

[0056] The order information displayed on the order payment interface allows the user to check the specific content of the order, thereby ensuring that the amount actually paid by the customer is consistent with the goods or services actually purchased by the customer and avoiding payment errors.

[0057] Figure 4 is a schematic diagram of an order payment interface according to an embodiment of the present disclosure; in Figure 4 In the shown order payment interface, at least one payment control includes a card swiping payment control and a code scanning payment control. Above at least one payment control is the order information. After the user confirms that the order information is correct, they can select one of the payment controls as the target payment control for payment according to their needs.

[0058] Step S130, in response to the payment instruction input based on the target payment control in at least one payment control when the user checks that the order information is correct, provide a payment result interface.

[0059] In some embodiments of the present disclosure, after the user determines that the order information displayed on the order payment interface is correct, the user may select a suitable payment control from at least one payment control as the target payment control according to factors such as payment method availability, payment convenience, personal preference, payment security, and payment methods supported by the merchant; after the user clicks the target payment control, the POS terminal will obtain a payment instruction and send the payment instruction to the payment gateway or the payment system of the bank for verification. After the payment gateway or the payment system of the bank receives the payment instruction, it will verify the integrity and legality of the payment instruction to confirm whether the payment instruction is valid; if the payment instruction is valid, the payment gateway or the payment system of the bank will return a payment authorization confirmation, indicating that the payment can continue to be processed. At this time, the payment result interface provided by the POS terminal is a payment success interface; if the payment instruction is invalid, the payment gateway or the payment system of the bank will return a failure response. At this time, the payment result interface provided by the POS terminal is a payment failure interface. In particular, for security reasons, the POS terminal may encrypt the payment instruction (such as using encryption algorithms such as Secure Sockets Layer (SSL), Transport Layer Security (TLS), etc.), and then send the encrypted payment instruction to the payment gateway or the payment system of the bank through an encrypted channel.

[0060] Taking the target payment control as the card - swiping payment control as an example, after the user clicks the card - swiping payment control, the POS terminal will prompt the user to insert the bank card or swipe the card; at this time, the POS terminal reads the magnetic stripe or chip information of the bank card and obtains the payment instruction.

[0061] Taking the target payment control as the code - scanning payment control as an example, after the user clicks the code - scanning payment control, the POS terminal will generate a QR code or display a payment code, and the user can make a payment by scanning the QR code or the payment code; at this time, the POS terminal obtains the payment instruction based on the payment information read from the QR code in the user's code - scanning operation.

[0062] The payment result interface is usually used to clearly display the transaction result to the user and provide detailed information about the transaction. The core function of this payment result interface is to clearly display the payment status, amount, merchant information, etc., to ensure that the user has a clear understanding of the payment transaction. In addition to the above information, the payment result interface can also provide convenient follow - up operation options for the user, such as refund, invoice printing, evaluation, etc., enabling the user to continue to have a good experience after the payment is completed.

[0063] Figure 5It is an example diagram of a payment result interface where the payment is successful in an embodiment of the present disclosure; in this payment result interface, the transaction result is displayed at the top, relevant transaction information is displayed in the middle part, and subsequent operation options "Return to Home Page" and "Print Receipt" are provided at the bottom, so that users can perform operations such as order query and other order payments after payment, or provide receipts to guarantee after-sales service for customers.

[0064] The POS terminal payment method provided by the present disclosure realizes POS terminal payment based on a simplified number. Since the simplified number is more concise, easier to remember and input than the traditional order number, this POS terminal payment method solves the problem in the prior art that with the rapid development of e-commerce and the explosion of the order volume, the format and length of the order number become more and more complex and lengthy, which not only increases the difficulty of manual input, but also is prone to errors, affecting the efficiency and accuracy of transactions.

[0065] Furthermore, the POS terminal payment method provided by the present disclosure may further include step S140 as shown Figure 6 before step S110.

[0066] Step S140: Provide a main interface.

[0067] In some embodiments of the present disclosure, the main interface provided by step S140 is the main screen of the POS terminal that users see when making a payment through the POS terminal. It carries necessary functional modules during the payment process and helps users complete payments, queries and other related operations efficiently.

[0068] The content displayed on the main interface in step S140 includes a collection control; in addition to the collection control, the content displayed on the main interface may further include one or more of a find order control, a transaction list control, a card balance check control, a group purchase verification control, and a terminal setting control, etc. Figure 7 It is an example diagram of the main interface in an embodiment of the present disclosure; Figure 7 The main interface shown is provided with a collection control, a bill control, a refund control, a shift handover control, an installment control, and an app store control.

[0069] At this time, step S110 is specifically to provide an order query interface in response to the operation of the collection control received from the user.

[0070] The main interface of the POS terminal is usually the initial interface displayed after the POS terminal is turned on or started; when a user needs to make a payment through the POS terminal, they can click on the collection control on the main interface, so that the POS terminal receives the operation of the collection control from the user. When the POS terminal receives the operation of the collection control from the user, it performs an interface jump to provide an order query interface.

[0071] Regarding step S130, in some embodiments of the present disclosure, it may include steps S131 to S132 as Figure 8 shown.

[0072] Step S131, in response to the payment instruction input by the target payment control in at least one payment control when the user checks that the order information is correct, provide a payment confirmation interface.

[0073] In some embodiments of the present disclosure, the payment confirmation interface in step S131 is an interface used to display payment information and confirm it when the payment information is correct during the payment process.

[0074] Figure 9 It is an example diagram of the payment confirmation interface of an embodiment of the present disclosure. In Figure 9 the shown payment confirmation interface, the payment information is displayed in the form of a pop-up box to guide the user to make a response.

[0075] Step S132, in response to the payment confirmation instruction input by the user based on the payment confirmation interface, provide a payment result interface.

[0076] In some embodiments of the present disclosure, after the user confirms that the payment information displayed on the payment confirmation interface is correct, the user can click the confirmation control on the payment confirmation interface to enable the POS terminal to receive the payment confirmation instruction input by the user based on the payment confirmation interface.

[0077] By performing payment information confirmation before payment through steps S131 to S132, the correctness of transaction information can be ensured, the error rate of operations can be reduced, and the transparency of payment can be improved.

[0078] Regarding step S132, in some embodiments of the present disclosure, it may include steps S1321 to S1322 as Figure 10 shown.

[0079] Step S1321, in response to the payment confirmation instruction input by the user based on the payment confirmation interface, provide a signature interface.

[0080] In some embodiments of the present disclosure, the signature interface in step S1321 is an interface for the customer to confirm the transaction through an electronic signature after confirming the order information and payment method during the POS terminal payment process.

[0081] Figure 11 It is an example diagram of the signature interface of an embodiment of the present disclosure.

[0082] Step S1322, in response to the signature confirmation instruction input by the user based on the signature interface, provide a payment result interface.

[0083] In some embodiments of the present disclosure, on the signature interface, the user can operate the confirmation control on the signature interface after signing through the touch screen of the POS terminal, the signature pad of the POS terminal peripherals or other input devices, as an authorization for payment, so that the POS terminal receives the signature confirmation instruction input by the user based on the signature interface. If the signature is incorrect, the signature can be re-entered through the rewrite control.

[0084] The electronic signature function is provided through steps S1321 to S1322 to ensure that the user agrees to the transaction amount and payment method, enhance the security of payment, prevent fraud, provide transaction vouchers, and meet compliance requirements.

[0085] Further, in the POS terminal payment method provided by the present disclosure, when the payment result interface in step S130 is a payment success interface and the payment success interface displays a voucher control, after providing the payment result interface through step S130, it may further include steps S150 as Figure 12 shown.

[0086] Step S150, in response to the operation of the voucher control received from the user, controls to provide the payment voucher of the order to be queried.

[0087] In some embodiments of the present disclosure, when the POS terminal is built-in with a printer, the way to control the provision of the payment voucher through step S150 can be to control the built-in printer to print the payment voucher; the way to control the provision of the payment voucher through step S150 can also be to control to provide the payment voucher by means of text message, email, two-dimensional code, etc. The payment voucher may include merchant information, transaction details (such as goods, amount, time, etc.), payment method, transaction status and other contents.

[0088] After the payment is successful, the payment voucher is provided through step S150 as a reference basis for transaction disputes or after-sales, improving the transparency and traceability of the transaction.

[0089] Regarding step S120, in some embodiments of the present disclosure, it may include steps S121 to S122 as Figure 13 shown.

[0090] Step S121, in response to the order query instruction of the order to be queried input by the user based on the order query interface received, controls to send the order query instruction to the server, so that the server determines the relevant order number according to the simplified number carried in the order query instruction and obtains the order information according to the relevant order number and then returns it.

[0091] Step S122, in response to the order information returned by the server, provides an order payment interface.

[0092] In some embodiments of the present disclosure, after the POS terminal receives the order information returned by the server, it may generate an order payment interface according to the order information and then provide the order payment interface through step S122.

[0093] Obtaining the order information from the server through steps S121 to S122 can support multi-terminal operations and improve the consistency of remote operations.

[0094] In some embodiments of the present disclosure, when the server receives an order query instruction sent by the POS terminal, the specific processing process of the server may include: the server responds to the received order query instruction carried with a simplified number sent by the POS terminal, and obtains the order number related to the simplified number (the code used to uniquely identify each order in commercial transactions); obtains the order information according to the order number; controls to send the order information to the POS terminal.

[0095] This order number is generated by the server in response to the settlement request sent by the user terminal; the simplified number is the number obtained by the server after generating the order number, associated with the order number, and sent to the user terminal for the user to view and then input on the POS terminal.

[0096] The process for the server to process the settlement request may include: the server responds to the received settlement request sent by the user terminal, obtains the order information according to the settlement request and generates an order number; obtains the simplified number of the order number; controls to send the simplified number to the user terminal for the user to input on the POS terminal.

[0097] In some embodiments of the present disclosure, after the buyer selects the goods, the selected goods can be entered on the user terminal by the buyer himself or by the seller; after the goods entry is completed, the buyer or the seller inputs a settlement instruction on the user terminal; the user terminal responds to the received settlement instruction and sends a settlement request carrying the information of the selected goods (such as a list of goods, quantity, unit price, etc.) to the server. Among them, the way to enter the selected goods on the user terminal can be to manually input the goods information through a keyboard or touch screen, click or select goods from the displayed list of goods, scan the bar code or two-dimensional code on the goods through a bar code scanner or camera, use a radio frequency identification (RFID) reading device to scan the RFID tag on the goods, or automatically match the goods information through image recognition technology, etc.

[0098] In particular, to facilitate the processing and differentiation of different orders and support subsequent processes such as order management, statistical analysis, and payment processing, in addition to the information of the selected goods, the settlement request may also carry additional information such as the buyer ID, seller ID, terminal number, timestamp, etc. Among them, the buyer ID can help the seller and the system identify the user's identity, ensure the correctness and security of the transaction process, and is also helpful for subsequent user behavior analysis, account management, etc.; the seller ID can help the system distinguish orders from different sellers, ensure the correct attribution of orders, and is also helpful for statistical and summarizing the sales data of the seller; the terminal number can help the system determine which specific device initiated the order request, provide the source of the transaction, so as to trace the origin in case of anomalies or disputes; the timestamp can ensure the uniqueness of the generation time of each order, prevent the occurrence of duplicate orders due to system problems, and can also help the system manage the entire life cycle of the order.

[0099] In addition to the above information, the settlement request may also carry promotion information (used to transmit relevant promotion codes or discount information to ensure the correct use of discounts when generating orders), terminal IP address (used for security verification to prevent malicious operations), and other information.

[0100] The server can obtain order information based on the information of the selected goods carried in the settlement request. The obtained order information may include the order generation time, commodity information, amount information (such as including the total commodity amount, promotion or discount amount, tax amount, and the final amount to be paid), transaction information (such as including buyer information, seller information, payment status (initially "pending payment")), other information (such as including supplementary instructions of the user or the system for the order, delivery information, inventory occupancy information), etc.

[0101] The server can generate an order number based on methods such as Universally Unique Identifier (UUID), hash algorithm, auto-incrementing ID, or predefined rules. Among them, generating an order number based on predefined rules means creating a unique order code according to a set of pre-determined standards or patterns; these rules are usually specified according to factors such as business requirements, data management requirements, and operation processes; common elements of predefined rules may include: time-related elements, random number elements, business type identification elements, user information elements, etc.

[0102] In particular, to ensure the integrity, legality, accuracy, and security of the settlement request, the settlement request can be first verified before generating the order number, so as to ensure the accuracy, compliance, and security of order generation. Among them, the methods for verifying the settlement request may include: checking whether the commodity information is complete and the format is correct, verifying whether the identity is legal, etc.

[0103] In some embodiments of the present disclosure, for the convenience of management and to simplify numbering, optional simplified numbers can be generated in advance according to the number of digits of the number and the optional simplified numbers can be placed in a database, so that the server can directly obtain the simplified numbers from the database. In particular, to improve the reading efficiency and high-concurrency processing ability, placing the optional simplified numbers in the database can specifically be to place the optional simplified numbers in the Zset ordered set of the Redis database.

[0104] In some embodiments of the present disclosure, after obtaining the simplified number of the order number, the simplified number can be associated with the order number for subsequent order queries.

[0105] In some embodiments of the present disclosure, after the user terminal receives the simplified number sent by the server, the user terminal can control the display of the simplified number, enabling the user to view and enter the simplified number on the POS terminal. There can be a time difference between the user terminal display and the user input on the POS terminal. The POS terminal ultimately used by the user can be one of multiple POS terminals and can be selected based on functions or load balancing, etc.

[0106] To facilitate the server's timely understanding of the payment status, when the user terminal displays the simplified number, a payment completion control can also be set; after the user completes the payment through the POS terminal, the "payment completion control" can be operated. In response to the operation instruction received for the "payment completion control", an order status update request is sent to the server, causing the server to update the status of the order from "pending payment" to "paid".

[0107] Further, to ensure that in a concurrent environment, multiple requests do not simultaneously process the order pointed to by the same order number, avoiding data conflicts and inconsistencies, the server can adopt a lock mechanism to control order information; when the order information is controlled by the lock mechanism and the acquisition fails, the order payment interface provided in step S120 is specifically a failure interface that responds to the failure information sent by the server and displays the failure information.

[0108] In some embodiments of the present disclosure, when the server fails to obtain the order information, a failure message is sent to the user terminal, causing the user terminal to provide a failure interface that displays the failure message in response to the failure message sent by the server, informing the user that the payment process cannot continue.

[0109] During this process, the specific process by which the server obtains order information based on the order number may include: The server requests to lock the order number; if the order number requested to be locked is already locked, it cannot be locked again, and the locking fails; when the locking fails, failure information is obtained, and the failure information is used to be sent to the POS terminal for failure handling. If the order number requested to be locked is not locked, the order number can be locked, and the locking is successful; when the locking is successful, the order information is obtained based on the order number.

[0110] In some embodiments of the present disclosure, a locking failure indicates that another POS terminal is performing a payment operation related to the order number. To avoid concurrent conflicts or data inconsistencies, the current request needs to wait or abort. Therefore, the user is informed of the failure information when the locking fails. The failure information can be an error or a message prompting the user to retry later.

[0111] In particular, when the locking fails, a retry mechanism can also be executed, that is, wait and then request to lock again when the locking fails; random delays or exponential backoffs (such as increasing the interval for each retry) can be added during the retry to reduce contention.

[0112] To prevent deadlocks, improve the throughput of the server, and ensure the execution of other tasks, after a certain order number is locked, the server can determine whether the order number meets the lock release conditions (such as payment completion, error or exception occurrence, timeout or expiration, external event trigger, etc.); if it is determined that the order number does not meet the lock release conditions, the above judgment process is repeatedly executed until the lock release conditions are met or the end condition is reached; if it is determined that the order number meets the lock release conditions or the end condition is reached, the lock of the order number is released.

[0113] To improve the availability and reliability of the simplified number, the simplified number can be obtained by the server based on a primary-backup asymmetric data storage mechanism. In this architecture, the primary database stores the main simplified numbers and serves as the default data source; the backup database stores the remaining simplified numbers; when the primary database is unavailable, the simplified numbers are provided by the backup database. At this time, the server is specifically used to attempt to retrieve the simplified number from the primary database; in response to the attempt failing, retrieve the simplified number from the backup database; in response to the attempt succeeding or retrieving successfully from the backup database, lock the simplified number.

[0114] During the process of locking the simplified number, the server is also used to obtain the order status of the order to be queried with the simplified number and the locking duration of the simplified number; determine whether the simplified number meets the number release condition according to the order status and the locking duration; in response to the simplified number meeting the number release condition, release the simplified number and put the simplified number back into the retrieved database. The server is also used to, in response to the simplified number not meeting the number release condition, execute the determination of whether the simplified number meets the number release condition according to the order status and the locking duration until the termination judgment condition is reached, and then release the simplified number and put the simplified number back into the retrieved database.

[0115] Among them, the order status is that the order payment is completed, the order is cancelled, or the order is not paid. The number release conditions include: the locking duration exceeds the locking duration threshold and the order status is that the order is not paid; or, the locking duration does not exceed the locking duration threshold and the order status is that the order payment is completed or the order is cancelled.

[0116] In this architecture, the process for the server to obtain the simplified number can include: judging whether the main database is available based on aspects such as the connectivity, responsiveness, and functionality of the main database; when it is determined that the main database is available, retrieving the simplified number from the head, tail, or random position of the main database, etc.; when it is determined that the main database is unavailable, retrieving the simplified number from the head, tail, or random position of the standby database, etc.

[0117] The simplified numbers stored in the main database and the standby database can be pre-generated according to the number of digits and then stored separately; specifically, the process for the server to generate optional simplified numbers and store them in the database can include: obtaining the number of digits, which is usually pre-set and can be set according to business requirements, etc., usually ranging from 6 to 8 digits; using methods such as loop nesting and recursion to obtain multiple optional simplified numbers according to the number of digits; taking the number of digits as 6 digits as an example, the obtained optional simplified numbers can be from 000000 to 999999, a total of 1 million; putting the multiple optional simplified numbers into the main database and the standby database respectively, and most of the optional simplified numbers can be stored in the main database.

[0118] In particular, in order to increase randomness, prevent security problems caused by sequentiality, and at the same time improve database performance, load balancing, and privacy protection, before putting the multiple optional simplified numbers into the main database and the standby database respectively, the optional simplified numbers can first be scrambled, and then the scrambled numbers can be put into the main database and the standby database respectively. Among them, the scrambling method can be hash scrambling, random scrambling, etc.

[0119] Taking the scrambling method as hash scrambling and the main database as the Zset of Resdis as an example, the optional simplified number can be used as the member and the hash value can be used as the score and put into the Zset. At this time, when retrieving, specifically, the simplified number is retrieved from the head of the Zset.

[0120] Releasing the simplified number and putting the simplified number back into the retrieved database can optimize the number management process and improve the utilization efficiency of the simplified number. When putting the simplified number back into the retrieved database, the retrieved database is the source database of the simplified number; the simplified number can be placed at the head, tail or any position of the retrieved database. Specifically, when the retrieved database is a Zset of Resdis, the simplified number can be put into the tail of the retrieved database.

[0121] The termination judgment condition can be reaching a preset waiting time or reaching a preset judgment count, etc. Taking the termination judgment condition as a fallback can avoid abnormal situations from causing the simplified number to be locked for a long time without release.

[0122] The locking duration of the simplified number is the length of time that the simplified number remains in the locked state. The process of judging whether the simplified number meets the number release condition can include: obtaining the retrieval time and the current time of the simplified number; subtracting the retrieval time from the current time to obtain the locking duration; judging whether the locking duration is less than the locking duration threshold; in response to the locking duration exceeding the locking duration threshold and the order status being that the order is not paid, or in response to the locking duration not exceeding the locking duration threshold and the order status being that the order payment is completed or the order is cancelled, it is determined that the simplified number meets the number release condition; otherwise, it is determined that the simplified number does not meet the number release condition.

[0123] The POS terminal payment method provided by the present disclosure can be used in a payment scenario where the order generation device and the payment device are not on the same entity.

[0124] In the POS terminal payment method provided by the present disclosure, the simplified number can be a number with a small number of digits such as 6 digits to ensure simple and correct input; and setting a lock during query can achieve mutually exclusive operations of different POS terminals for the same order number, thereby preventing duplicate payments, ensuring order status consistency, improving data integrity, avoiding inventory conflicts, and improving system security; in addition, putting back the simplified number when the number release condition is met can also reduce storage overhead, improve management efficiency, avoid overflow or shortage, enhance flexibility, reduce data conflicts and errors, and improve the user experience.

[0132] Step S260: The POS terminal provides an order query interface.

[0133] Step S270: The POS terminal, in response to the order query instruction of the order to be queried input by the user based on the order query interface, controls to send the order query instruction to the server.

[0134] In some embodiments of the present disclosure, the order query instruction carries a simplified number related to the order number of the order to be queried.

[0136] Step S290: The server obtains the order information according to the order number.
