Multi-frequency multi-purpose electronic tag and its application method

Abstract

The invention discloses a multi-frequency and multi-purpose electronic tag and an application method thereof. The electronic tag comprises a processor and a plurality of radio frequency (RF) front ends. The processor and the plurality of RF front ends are connected. The plurality of RF front ends are in information interaction with one another via the processor. The method comprises the steps of reading the RF data of an external RF reader-writer via one RF front end, receiving the RF data via the processor, sending a data reading command from another external RF reader-writer to another RF front end, converting the RF data by the processor based on the data transmission protocol, and sending the RF data to another external RF reader-writer from another RF front end. According to the invention, the electronic tag can be applied to RFID systems of different frequencies and can also be read by a handset having the NFC function. Meanwhile, the electronic tag is simple in structure and realizes the interconnection between RFID systems of different frequencies.

Description

technical field [0001] The invention relates to a multi-frequency and multi-purpose electronic tag and a using method thereof. Background technique [0002] RFID tag is a non-contact automatic identification technology, which is widely used in logistics, retail, medical, transportation, food and other industries, as well as identification, product anti-counterfeiting, asset management and other fields. Usually, the electronic tag is composed of a coupling element and a chip. The contactless coupling of the signal is realized between the electronic tag and the reader through the coupling element. In the coupling channel, energy transmission and data exchange are realized according to the timing relationship. At present, the carrier frequencies commonly used for data transmission of electronic tags are generally 125KHZ, 134.2KHZ, 13.56MHZ, and 2.4GHZ, etc., and each electronic tag corresponds to only one carrier frequency. Tags with different carrier frequencies are not interc...

Problems solved by technology

[0005] However, low-frequency access control electronic tags and animal identification electronic tags are not so convenient, and special handheld card reading devices or other special equipment must be used, which greatly reduces the flexibility and convenience of low-frequency electronic tags.

For example, if an animal using a low-frequency electronic tag is lost, it is necessary to find a special agency and use a special card reader to identify the animal.
