How can a product be tracked during the flow of the field to a retail store or a food service provider? How to identify the direct source and direct recipient of the product? How to retrieve problem products from the supply chain? And the like, become key issues for realizing product traceability. Food safety, product tracing and product recalling are the most concerned focuses of governments and industries at present, and enterprises face a great deal of tracking and tracing requirements.
One effective means to solve these problems is: the traceability of food is realized, and the traceability of all links from raw materials to production and processing to transportation and sale is realized by adopting international standards. Currently, the traceability technology accepted and adopted by most international countries is proposed by the international code society (GS1), and the traceability technology based on the commodity bar code has formed a mature global traceability standard and application support, and provides a set of standard traceability processes for each participant in the supply chain, so as to help enterprises strengthen business processes to meet current challenges.

the server includes:
the API service module is used for receiving a transaction request sent by a buyer terminal;
the equipment authentication management module is used for carrying out validity verification on the transaction terminal according to the transaction terminal signature information in the transaction request;
the data acquisition module is used for sending a transaction result to the transaction terminal after transaction confirmation is carried out on the data acquisition module and the purchaser terminal so that the transaction terminal can generate a first traceability two-dimensional code;
the data analysis engine module is used for comparing the GID codes of the buyers with the GID codes of the sellers according to the transaction records sent by the transaction terminal to obtain the tracing results of the commodities in the corresponding transaction records;
and the commodity tracing module is used for generating a second tracing two-dimensional code according to the tracing result of the commodity in the corresponding transaction record and acquiring the tracing results of the bulk food and the agricultural products.
The invention provides a method for generating traceability two-dimensional codes for bulk food and agricultural products, which is used for realizing the whole chain tracing monitoring of the bulk food (agricultural products) based on electronic transaction by deploying transaction terminals in a production base, a wholesale market and a vegetable market in a whole supply chain covering the bulk food and the agricultural products.
The invention needs to complete member registration of merchants based on the mobile terminal APP/browser in a production base, a wholesale market and a dish market where a trading terminal is deployed. Firstly, a merchant fills in member information and submits bank account information, then a unique GID code and a password distributed by a system for the merchant are obtained, eID of a transaction terminal is associated (realized by scanning a two-dimensional code on the transaction terminal), and meanwhile, a virtual member card (comprising a member two-dimensional code, a code scanning function, data query and the like) can be generated in APP software. After the member successfully registers, the system opens an electronic transaction channel for the merchant and issues the GID code to the transaction terminal corresponding to the eID through the data acquisition management module.
The member uses the commodity standard library (which can be synchronous with the server) in the commodity sales management module pre-installed in the transaction terminal to check and configure the commodities for the member to run and sell, a sales interface is generated, meanwhile, the standard code MID of the commodities is generated, and the commodities which do not exist in the commodity standard library can be added by the merchant and are synchronous to the commodity standard library in the commodity management module of the server.
The merchant selects the commodity, inputs the price, obtains the commodity attribute (such as weight) and generates the order and the corresponding transaction two-dimensional code by using the sales interface. Each order is a 'virtual package', and the trading two-dimensional code comprises attributes such as a trading terminal eID, a server domain name or an IP address, an order number, a trading serial number, a commodity, a standard code MID and the like.
The transaction terminal is pre-installed with a commodity sales management module, commodity synchronization, commodity selection, price input and transaction amount calculation of bulk food (agricultural product) sales are realized through the commodity sales management module, and a transaction two-dimensional code containing the information is generated by combining a unique identification number (eID) of the transaction terminal and an IP address or a domain name of a Server (Server).
A purchaser (which can be a merchant in a wholesale market, a merchant in a dish market or a common consumer) scans a transaction two-dimensional code through a terminal device (namely a purchaser terminal) with a two-dimensional code identification function or a mobile terminal APP and then sends a transaction request to an API service module of a Server (Server), wherein the transaction request has information such as a unique identification number (eID) of a transaction terminal, a transaction amount and a transaction terminal key.
The API service module of the Server firstly authenticates the legality of the transaction terminal according to the transaction terminal key, and verifies the interaction of transaction confirmation with a buyer after the transaction terminal passes the verification. If the buyer calls the third party payment client through the mobile terminal APP to confirm the payment, the API service module of the Server (Server) together with the third party payment client information used by the buyer and the transaction request initiates a payment request to the third party payment according to the format of the corresponding third party payment access, then the third party payment and the buyer directly complete the interaction required by the payment, and finally the API service module of the Server (Server) receives the result of whether the payment is successful or not and feeds the result back to the transaction terminal through the data acquisition management module to perform corresponding prompt so as to complete the whole payment process.
The transaction terminal generates first traceability two-dimensional codes for all commodities related to the transaction by using the transaction record, points to the traceability link of the commodities in the current transaction, uploads the first traceability two-dimensional codes and the transaction record to the data acquisition and management module of the server through the Internet, and then stores the data acquisition and management module to the data warehouse module.
If the purchaser selects to confirm the transaction (but not to pay) through the mobile terminal APP, the API service module of the Server (Server) sends a transaction request containing the commodity standard code MID and the transaction amount to the API service module of the Server (Server) to send a transaction confirmation request, and after receiving a payment result confirmed by the transaction, the API service module feeds the transaction result back to the transaction terminal to carry out corresponding prompt so as to complete the whole transaction process.
