In the past two years, many new unmanned self-service devices have emerged with the help of new retail and the sharing economy. Nowadays, the use of vending machines is quite extensive. Coupled with the emergence of the epidemic, the use of vending machines has brought a lot of convenience to our lives, which can realize contactless shopping and reduce the spread of the virus.

The working principle of unmanned vending machines is very simple, mainly based on identifying RFID tags or camera images to identify shipments. RFID requires additional product tags, which will consume a lot of manpower and material resources. Image recognition technology is more promising.
