[0002] The existing radio frequency identification (RFID) tags include UHF tags and NFC tags. Among them, UHF tags have long reading distance, strong flexibility, high recognition efficiency, and are widely used in clothing, logistics, medicine, tobacco and other industries. NFC tags have high security, large storage capacity, and can communicate through mobile phones. They are widely used in libraries, subway tickets, game cards and other industries.

[0003] However, most of the products on the market currently use UHF tags and NFC tags independently, and are unable to combine the advantages of the two. Some products simply put the two tags side by side to form a dual-frequency tag, which is not only inconvenient to use, but also increases the size of the tag. At the same time, there is no data association between the UHF tag and the NFC tag, which limits the scope of application. It cannot be applied to IoT devices that require different recognition angles, and its scope of application is relatively limited. Summary of the invention
