Abstract: A method and a device for reading RFID/UHF label based on an audio interface are disclosed. According to the method, a built-in software module in an electronic device converts a first digital signal into an analog signal capable of being transmitted via the audio interface; the analog signal received by the audio interface is converted into a second digital signal via an audio communication circuit; then the RFID/UHF controller for digital signal control reads information from the RFID/UHF label; the RFID/UHF controller modulates and sends signals of a plurality of different frequency points, and the signal of every frequency point forms a signal channel. Compared with the prior art, the present invention can keep long-distance communication between the electronic device and a plurality of labels.

Abstract: The tag comprises a bearing substrate, a first adhesive layer, a resin film, an etching antenna layer, a chip, a first insulating layer, a conductive circuit layer, a second adhesive layer, and a pattern-bearing layer. The resin film is disposed between the bearing substrate and the etching antenna layer. The etching antenna layer is etched by copper foil or aluminum foil. The conductive circuit layer and the etching antenna layer are combined to construct a compound high-frequency antenna of the fragile RFID electronic tag. The conductive circuit layer fulfills a communication of a jumper wire on the etching antenna layer. The first insulating layer is disposed between the conductive circuit layer and the etching antenna layer. The chip is connected to the etching antenna layer. The etching antenna layer, the conductive circuit layer, the first insulating layer and the chip are combined to construct a core assembly.
