With the popularization and application of the 2D code access control, it is stated in "Supply and Marketing Headquarters: Promoting the Integration of Urban and Rural Sanitation" that online recycling and other new recycling methods are carried out by using technologies such as Internet, cloud computing, big data and artificial intelligence, so as to broaden recycling channels, promote "Internet waste recycling" and build an online and offline integrated environmental service system.

       Through the two-dimensional code access control, the information management of "Internet waste product recycling" is promoted, and all links of garbage classification are intelligently managed from garbage classification publicity, garbage classification delivery, garbage classification collection and garbage transportation.

      At present, in China, garbage disposal methods are different in different cities. According to the comprehensive situation of each place, it is set according to local conditions. For example, a company in Shanghai adopts the system of rewarding garbage classification points or returning red envelopes, encouraging residents to classify garbage, installing two-dimensional code access control on garbage recycling equipment, and docking with intelligent garbage classification system, so that residents can scan code to put garbage and collect red envelopes.

       However, in life, we see more intelligent garbage sorting and recycling machines, that is, the garbage is put in by scanning the code through the QR code or swiping the card out of the box. The system will calculate the amount according to the nature of the recycled products, and the funds will be deposited in the resident classification card. Residents can apply to withdraw the money from their accounts, and can also exchange points for daily necessities online.

       MASUNG QR code scanning module MS-7740 is suitable for "Internet waste product recycling" equipment. It is small in size and easy to install in highly integrated environment. It has industrial-grade red fill light, supports reading in the sun and completely dark environment, supports voltage reset with wide voltage of 3.6-6V, supports code reading in motion at 2M/S, and recognizes at ultra-high speed. It has built-in RS232 and USB interfaces and buzzer.

        Shenzhen MASUNG is a professional supplier and manufacturer of OEM and ODM two-dimensional code access control scanning heads, two-dimensional code scanning modules, two-dimensional code scanners and access control scanning modules, providing solutions for the global two-dimensional code access control to realize "Internet waste goods recycling".
