RFID technology boosts the fresh food industry to make food fresher

　　With the rapid development of radio frequency identification technology, its application in various fields has a good reputation, especially the advantages of radio frequency identification technology in the application of fresh food cold chain logistics. In recent years, the chain distribution system has become more and more prosperous. The food circulation pattern has changed from traditional retail to chain sales. The requirements for product control are also very high. The technical requirements of cold chain logistics are also constantly innovating to ensure the freshness of food ingredients.

　　As a new type of automatic identification technology, RFID technology has gradually become an indispensable technical tool and means for enterprises to improve cold chain logistics management, reduce costs, and realize enterprise management information, especially to enhance the core competitiveness of logistics enterprises.

　　RFID technology in the circulation of fresh food:

　　1. The refrigerated truck of the distribution center arrives at the designated delivery point for unloading on time. The staff uses a handheld RFID reader to read all the cargo information at one time and confirm the consistency of the cargo information with the order form. If the information is consistent, update the relevant data in the retailer's sales system.

　　2. The staff will immediately push the goods into supermarkets and vending machines for sale on the shelves. Frozen food is put on the shelves in a timely manner to ensure that supermarkets and vending machines will not appear "out of stock" or "out of stock" phenomena, so as to meet the consumer demand of consumers and the sales demand of retailers.

　　3. The supermarket or unmanned vending machine has an RFID antenna above the fresh food, and then reads the information in the RFID tag on each product package through the antenna and reader to automatically identify the newly added product. At the same time, the RFID reader on the freezer can read the temperature information of the freezer in real time and feed it back to the system management center in time to ensure that the temperature of the freezer is within a certain range to ensure the freshness of fresh food.

　　4. Customers take a certain amount of goods from the freezer, the RFID reader can automatically obtain the relevant information of the taken goods, and timely send information to the automatic replenishment system of the supermarket or unmanned vending machine.

　　5. The customer pays. RFID tags are affixed to the outer packaging of frozen foods. When a customer pushes the shopping cart through the door equipped with an RFID reader, the reader can identify the type, quantity, amount and other information of the goods in the shopping cart at one time. The computer screen will display the total amount of the customer's consumption, and then the customer pays and leaves.

　　6. When the customer leaves after consumption, the sales system of the supermarket or unmanned vending machine will be automatically updated immediately, and all the information of the products sold and the sales amount will be recorded.

　　Due to the fact that fresh food is not easy to store, the operation process is simplified and the intermediate links are shortened. Let the freshness of the ingredients minimize the precipitation of time. Therefore, the RFID technology is used to quickly identify fresh foods, automatically collect data, and reduce various records and statistics during transportation. This greatly saves the time of out/in storage and improves the operation. Efficiency has increased the freshness preservation of fresh products and promoted the rapid development of the fresh food industry
