As the Internet of things continues to mature, more and more widely used, so the actual scene demand also continues to promote the further development of Internet of things technology. Because the RF signal of RFID technology has interference to human body, metal and liquid. The human body will absorb RF microwave, liquid and metal can not penetrate the RF signal, so the application of RFID radio frequency will be interfered by metal and liquid and can not be applied in its field. At present, only by overcoming these technical difficulties can the Internet of things be implemented in a large area!

Application and function of RFID in metal and liquid

At present, a variety of metal resistant and flexible metal resistant tags have been put into use, such as metal RFID asset management, metal equipment, construction and so on. With the rise of unmanned retail, breaking through the restrictions of liquid drinks on UHF RFID radio wave is an urgent problem for the Internet of things industry.

Some R & D teams have successfully developed new RFID electronic tags, innovated the labeling method of RFID tags, and used flag tags to avoid the impact of liquid on RFID. The liquid label can be directly pasted on the surface of liquid non-metallic packaging bottle, successfully breaking through the restrictions of RFID technology in the use of liquid goods!

The tag not only expands the application scope of RFID, but also provides more convenient and reliable technical support for the development of unmanned retail. Conventional superscript, simple and convenient: adopt conventional superscript, simple and efficient. Moreover, behind the conventional labeling method is to provide the basis for the standardization of RFID label labeling and remove obstacles for the development of automatic labeling technology. Small size, beautiful display, RFID tags pasted on the surface of goods, and the size is similar to the conventional bar code, which has little impact on its display. It does not need to reserve label position in the display, so as to improve the beauty and space utilization. To enhance the stability of the technology, in the process of using the flag label, consumers will inadvertently take and put the goods, which will cause the RFID tag folding phenomenon, thus affecting the label performance, while the liquid label can avoid this situation and increase the reliability of the technology.

The successful research and development of liquid label will not only meet the existing demand of unmanned retail, but also bring more application value, which means that RFID can be used to collect a large amount of consumer data of various drinks, liquid cosmetics, alcohol and other commodities. Especially in the field of cosmetics, the liquid category accounts for a large proportion of its products, and consumer preferences will have a great impact on its sales. With RFID and reader, it can record real consumer behavior data such as sample trial times and duration, and analyze the actual sales situation, which can provide data support for the formulation of sales strategy.

The successful research and development of liquid RFID electronic tags is not only for the Internet of things industry, but also a step up in the development process of RFID, making the management of metal and liquid items once again join the RFID Internet of things world. As a kind of data carrier, RFID electronic tag can play the role of identification, item tracking, information collection and so on. At present, RFID tags have been used in a wide range of fields. The RFID system composed of RFID tag, RFID reader, RFID antenna and application software is directly connected with the corresponding management information system. Intelligent automatic acquisition and identification function.
