Unmanned supermarket, you may have heard that shopping can be completed by choosing what you want and paying by mobile phone or other means. Recently, Southwest University has unmanned cartons. Besides school supplies, there are many daily necessities in the carton. After selecting the goods, the students consciously pay.

There is a small jar in the carton, which is used to collect and put change, and the QR code of WeChat and Alipay is attached on one side. Students can take away the small commodities they want by putting in change or scanning the code to pay.

At lunch time, many students packed their books and prepared to eat, and stopped to observe when passing by the carton. In the meantime, a girl selected a pack of paper towels from the box and paid with WeChat. It was also found in the downstairs of several dormitories far away from the supermarket and in front of several public teaching buildings. Many students are quite novel about the emergence of unmanned cartons: "What I only saw on the news did not expect to appear in school."
