Double-frequency reuse antenna RFID (Radio Frequency Identification Devices) tag having dialing communicating function

Abstract

The invention provides a double-frequency reuse antenna RFID (Radio Frequency Identification Devices) tag having a dialing communicating function. The double-frequency reuse antenna RFID tag having the dialing communicating function at least comprises a radio frequency 2.4GHz reuse antenna, a high-frequency 13MHz reuse antenna, an embedded processor, a keyboard, a displayer, a charging battery, a UIM (User Identity Model) /SIM (Subscriber Identity Module) and a phone module; the embedded processor is respectively connected with the radio frequency 2.4GHz reuse antenna, the high-frequency 13MHz reuse antenna, the embedded processor, the keyboard, the displayer, the charging battery and the phone module; the charging battery is also connected with the high-frequency 13MHz reuse antenna. The double-frequency reuse antenna RFID tag having the dialing communicating function can be applied to the application fields requiring identity identification, interaction and payment due to the fact that the dialing communicating function can be achieved through introduction of the phone module, such as that a campus card is used for remote checking attendance, applied to training teaching for classroom interactive questions and answers, applied to electronic payment and the like.

Description

Technical field [0001] The invention relates to the field of radio frequency identification, in particular to a dual-frequency multiplexing antenna RFID tag with a dial-up call function. Background technique [0002] Radio Frequency Identification is RFID (Radio Frequency Identification) technology, also known as radio frequency identification. It is a communication technology that can identify specific targets and read and write related data through radio signals 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 ones. At present, RFID technology is widely used, such as libraries, access control systems, and food safety traceability. [0003] RFID tags are generally divided into active RFID tags and passive RFID tags. Passive RFID tags...

AI Technical Summary

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
