Problems solved by technology
[0004] With the development of technology, more and more circuits and devices are equipped on RFID tags. In terms of power supply, passive RFID tags cannot meet the power supply requirements. Currently, active RFID tags use batteries for power supply, and batteries are usually packaged in active In the card, when the power is exhausted in about 1 to 2 years, the card will be scrapped

The invention provides an RFID (radio frequency identification) tag with identity sensing and interaction functions. The RFID tag comprises a radio frequency2.4 GHz multiplex antenna and a high frequency 13MHz multiplex antenna. The radio frequency2.4 GHz multiplex antenna comprises an RF (radio frequency) sensing channel and an RF interaction channel, wherein in the work mode of identity sensing, the RF sensing channel is at least used for sending ID information to an external terminal; in the work mode of interactive communications, the RF interaction channel is at least used for achieving two-way transmission of communication data between the multiplex antenna and the external terminal. As for the high frequency 13MHz multiplex antenna, in the work mode of identity sensing, the high frequency 13MHz multiplex antenna is used for achieving close-distance sensing with the external terminal; in the work mode of charging, the high frequency 13MHz multiplex antenna is used for wireless charging of chargeable batteries. The RFID tag can be applied to the application fields in need of identity recognition, interaction and payment simultaneously; for example, the RFID tag can be applied to campus cards for remote checking attendance, or training teaching for interactive questions and answers at class, or electronic payment.
Description
technical field [0001] The invention relates to the field of radio frequency identification, in particular to an RFID tag with identity perception and interaction functions. Background technique [0002] Radio Frequency Identification (RFID) technology, also known as radio frequency identification, is a communication technology that can identify specific targets through radio signals and read and write related data without the need to establish mechanical or optical contact between the identification system and specific targets . Commonly used are low frequency (125k ~ 134.2K), high frequency (13.56Mhz), ultra high frequency, microwave and other technologies. RFID readers are also divided into mobile and fixed. At present, RFID technology is widely used, such as: libraries, access control systems, food safety traceability, etc. [0003] RFID tags are generally divided into active RFID tags and passive RFID tags. Passive RFID tags do not have their own power supply inside, ...
