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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for reading RFID/UHF label based on audio interface","description":"A method and a device for reading RFID/UHF label based on an audio interface are disclosed.
