Abstract
When shopping in a big supermarket, customers often encounter two inconvenient places. The first problem is that it is difficult to find the target goods. The second problem is that the checkout process takes a long time. In this paper, Radio Frequency Identification and two-dimensional code technology are used to solve these two problems. The intelligent supermarket system mainly contains the following four parts: (1) Using RFID technology, the system realizes rapid warehousing and outbound operation to reduce the checkout time to seconds. Using collision detection technology, the system can prevent multi label repeated extraction. (2) The WIFI, two-dimensional code, mobile phone and server are combined together to realize the positioning and navigation function of the products. (3) SCM and RFID can realize antitheft function. (4) The two-dimensional code and mobile phone are combined together, to achieve the supply channel query function. This system is not only applicable to supermarkets, but also can be used in the field of logistics, warehouse management, and indoor navigation and so on.
