Title:
RADIO FREQUENCY IDENTIFICATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/121793
Kind Code:
A1
Abstract:
The embodiments of the present application disclose a radio frequency identification method, for improving the success rate of radio frequency identification. The method of the embodiments of the present application comprises: an electronic tag receiving an energy signal transmitted by a helper by means of a first frequency band, and receiving a control signal transmitted by the helper by means of a second frequency band, the first frequency band being different from the second frequency band. The electronic tag demodulates the control signal from the second frequency band, and modulates, according to the control signal, the stored description information for describing the product onto a reflected signal, the frequency band of the reflected signal being the same as the first frequency band, and the electronic tag transmits, to a receiver, the reflected signal modulated with the description information.
