1. Low Cost: Vending machines take up minimal space and have low labor costs, embodying the new retail concept of unstaffed operations. Unlike unmanned supermarkets, which require a dozen staff to manage orders and adjustments, vending machines don't need salespeople. Consumers can purchase items self-servingly, and this simple, convenient method fully meets their needs.

2. Sales Assurance: Vending machines operate similarly to unstaffed supermarkets, allowing customers to pick up items before paying. This doesn't disrupt the shopping experience while also providing protection for vendors. The machines have an automatic identification system, where customers simply scan a QR code with Alipay or WeChat for automatic settlement, then collect their items—making the process more convenient for consumers.

3. Fast layout and wide coverage: Unmanned vending machines occupy less space, can be placed flexibly, and can be moved to new locations in real-time, quickly capitalizing on business opportunities. This is a significant advantage for companies aiming to rapidly capture the market. On the other hand, operating a cashless supermarket is not as straightforward; careful consideration of location is still essential. Suitable store location, size, and investment costs are all necessary factors to consider.

In the future, the unmanned retail industry will become increasingly intelligent. With the advancement of technology, China's unmanned vending machine technology will take great strides and is now moving towards the 5G era. Researchers will apply high-tech technologies to unmanned vending machines, which hold a significant position in the unmanned retail market. The unmanned retail industry will continue to rise in the future, and the unmanned vending machine industry will also become increasingly popular.
