Payment method and apparatus, related device, and system

A payment apparatus, applied to a processing server to process payment that is independently performed between a user equipment and a payment channel server, the payment apparatus comprising:

• at least one memory configured to store program code;
• and
• at least one processor configured to read the program code and operate as instructed by the program code, the program code comprising:
• payment order generation code configured to cause at least one of the at least one processor to generate a payment order bound to a merchant order generated by a merchant device by determining a corresponding item ID, of a service and/or a product for purchase, that is registered with the payment channel server, the merchant order corresponding to the service and/or the product provided by the merchant device and indicating a transaction price of the service and/or the product, wherein
• a plurality of item IDs are registered to the payment channel server and are associated with the same transaction price, and the payment order generation code is configured to cause at least one of the at least one processor to generate the payment order bound to the merchant order by:
• determining one item ID as the corresponding item ID, among the plurality of item IDs, in a polling manner, by periodically and sequentially supplying the plurality of item IDs to be assigned to the transaction price each time a payment pull-up request of the user equipment is received for the same transaction price, and binding the determined one item ID to the merchant order, and
• with respect to a plurality of merchant orders that correspond to a plurality of payment pull-up requests of the user equipment for the same transaction price and are bound to the one item ID:
• based on a payment via the payment channel server not having been made, statuses of the plurality of merchant orders are marked as not being yet matched, and
• based on the payment via the payment channel server being made for one of the plurality of merchant orders, the statuses of all the plurality of merchant orders are marked as being matched;
• payment voucher obtaining code configured to cause at least one of the at least one processor to obtain, from the user equipment, a payment voucher, wherein the payment voucher is provided from the payment channel server to the user equipment based on payment of the payment order by the user equipment using the payment channel server, wherein the payment voucher indicates one item ID, among the plurality of item IDs, used by the user equipment to complete the payment of the payment order;
• merchant order matching code configured to cause at least one of the at least one processor to match, based on the payment voucher, the merchant order bound to the payment order by using the one item ID;
• and
• service providing notification code configured to cause at least one of the at least one processor to transmit, based on the matched merchant order, a service/product providing notification for providing the service to the user equipment.

A payment apparatus, applied to a merchant device, the payment apparatus comprising:

• at least one memory configured to store program code;
• and
• at least one processor configured to read the program code and operate as instructed by the program code, the program code comprising:
• merchant order generation code configured to cause at least one of the at least one processor to generate a merchant order corresponding to a service and/or a product provided by the merchant device and indicating a transaction price of the service and/or the product;
• payment order generation request code configured to cause at least one of the at least one processor to transmit, to a processing server, a request for a payment order bound to the merchant order, the payment order being generated by the processing server based on determining a corresponding item ID, of the service and/or the product for purchase, that is registered with a payment channel server, wherein
• a plurality of item IDs are registered to the payment channel server and are associated with the same transaction price, and the merchant order generation code is configured to cause at least one of the at least one processor to generate the merchant order by:
• determining one item ID as the corresponding item ID, among the plurality of item IDs, in a polling manner, by periodically and sequentially supplying the plurality of item IDs to be assigned to the transaction price each time a payment pull-up request of a user equipment is received for the same transaction price, and binding the determined one item ID to the merchant order, and
• wherein with respect to a plurality of merchant orders that correspond to a plurality of payment pull-up requests of the user equipment for the same transaction price and are bound to the one item ID:
• based on a payment via the payment channel server not having been made, statuses of the plurality of merchant orders are marked as not being yet matched, and
• based on the payment via the payment channel server being made for one of the plurality of merchant orders, the statuses of all the plurality of merchant orders are marked as being matched;
• service providing notification receiving code configured to cause at least one of the at least one processor to receive a service/product providing notification from the processing server, the service providing notification being based on a payment voucher that is obtained corresponding to the payment order bound to the merchant order, wherein the payment voucher is provided from the payment channel server to the user equipment based on payment of the payment order by the user equipment using the payment channel server, wherein the payment voucher indicates one item ID, among the plurality of item IDs, used by the user equipment to complete the payment of the payment order;
• and
• service providing code configured to cause at least one of the at least one processor to provide, based on the service/product providing notification, the service and/or the product corresponding to a matched merchant order to the user equipment, the matched merchant order being matched to the merchant order bound to the payment order by using the one item ID.
