Unmanned supermarkets are fashionable new shopping that has become popular in the past two years. At present, most unmanned convenience stores on the market use RFID solutions. The advantages are: RFID technology is mature, various application cases and solutions are perfect, and equipment is widely used. . The disadvantage is that A, RFID signals are easily attenuated and shielded when encountering liquids and metals, and they are easy to be torn when they are stuck. B. Size and sensing distance are difficult to coordinate. C. Because there is no contact between the chip and the antenna, the missed reading is serious. D, The cost is high, the low frequency of RFID tags is 0.5-0.8 yuan, and the starting price of UHF RFID tags is just a few yuan.

The success of Amazon Go naturally moved the hearts of giants such as Alibaba. Through cooperation with high-tech companies, major companies have gradually made the new retail concept of unmanned supermarkets a reality. The emergence of unmanned supermarkets and RFID The use of technology is inseparable. According to the experience of local users in Shanghai, the products in the unmanned supermarket are all labeled with a kind of label.

Yes, this kind of tag is an electronic tag and an important part of the RFID system. The supermarket uses the omnidirectional tag H47 tag in the inlay series, which uses the latest true 3D technology of impinj, and the H47 uses tag dual antennas. The reading effect is not limited by the reader antenna, and can be well identified in 360 degrees in space. It is a major innovation in the field of UHF RFID. The electronic tag is combined with the read-write system in the automatic cash register to help consumers complete the payment.

As a wireless communication technology, RFID technology is very suitable for the concept of new retail. Therefore, it is understandable that RFID technology has become the hero behind the unmanned supermarket. In the case of combining RFID-related technologies, the unmanned supermarket also combines electronic monitoring and other technologies to make a real unmanned supermarket appear in front of people as perfectly as possible. Perhaps the birth of an unmanned supermarket will be like sharing a bicycle, there are many problems that need to be solved, but a more convenient economic lifestyle has become a trend of the times.
