Background technique

At present, the e-commerce network is more and more developed, and it is a trend to buy and sell fruits and vegetables through e-commerce. After the fruits and vegetables are ripe, many people choose to buy fruits and vegetables through the Internet. However, when buying fruits and vegetables through the Internet, they often cannot see the fruits and vegetables in advance. They can only decide whether to buy from the descriptions and pictures of the merchants, and cannot select the designated fruits and vegetables as the reality. To buy, when buying fruits and vegetables in reality, after picking them up, weigh and pay.

If the merchant allows the consumer to purchase the designated fruits and vegetables, it is necessary to ensure that the fruits and vegetables that the consumer receives are the fruits and vegetables designated at the time of purchase, and that the fruits and vegetables are not exchanged during the delivery and transportation of the merchant. Although the fruit and vegetable traceability mechanism can solve the source and quality problems of fruits and vegetables to a certain extent, it is attached to fruits and vegetables by QR code, barcode or other anti-counterfeiting marks. The label attachments will be torn off on fruits and vegetables. The possibility of going to other fruits and vegetables, in this case, can not solve the quality problem, can not guarantee that the fruits and vegetables that consumers get are the fruits and vegetables specified at the time of purchase.

Therefore, how to purchase the designated fruits and vegetables on the Internet and in reality has become a technical problem to be solved urgently.
