Symbol. However, in the process of purchase, sale, delivery, even washing and maintenance, these high-value goods must be out of the actual scope of ownership of the owner, and during this period, the preservation of high-value goods is particularly dangerous. important. For example, suppose a consumer carries a high-value garment they own to a laundromat and puts it into a coin-operated machine to initiate a washing or drying process. Since the washing or drying process takes a long time, the consumer may choose to leave the laundromat first, the standby device stops working and then returns to take out the laundry. However, if the consumer does not return to the laundromat before the machine stops working due to delays, then the younger one has the opportunity to open the machine to take out the clothes, which not only causes the loss of the consumer, but also causes trouble for the laundromat operator.

In addition, as traditional grocery stores gradually enter the history, convenience stores have long been a modern urban life because of the long service time and diversified service model, combined with the electronic operation of Jinliu, logistics and information flow. A missing link. Everyday trading activities such as purchasing food and beverage books, paying fine bills, booking tickets, withdrawing cash, and even sending laundry items are all done at convenience stores. In recent years, convenience stores have built dense access networks in urban settlements, thus attracting logistics companies to cooperate with them to facilitate the distribution of goods as a delivery and pick-up center.

A convenience store that picks up the goods; 2. The operator who operates the e-commerce portal transmits the goods order electronically to the goods supplier; 3. The goods supplier delivers the goods to the designated convenience store through the logistics provider and informs the consumers The store will pick up the store within the scheduled time. If the consumer does not pick up the goods in time, the goods will be returned to the goods supplier through the logistics provider; and 4. The consumer can choose to pay when picking up the goods, or choose to enter the e-commerce Prepaid account for the Golden Stream system of the website.

The above-mentioned logistics system involves the combination of the virtual path of e-commerce and the physical path of facilitating super-business, which is not only an innovative business model, but also directly promotes the booming of the online shopping market. However, this kind of logistics system is extremely effective in the distribution of general goods, but it is not safe for the delivery of high-value goods. If high-value goods are lost during the implementation of step 3 above, the logistics provider or convenience super-business is not only facing consumer complaints, but also more likely to suffer economic losses. Even if the convenience of super-business can be added with mechanical locks to strengthen the preservation measures for high-value goods, this method not only increases the labor management costs of the operators, but also prevents the criminals from using the identity of the delivery person or the consignee. To steal goods.
