Abstract
This disclosure provides a radio frequency identification method and system, to improve a radio frequency identification success rate. The method includes: An electronic tag receives an energy signal transmitted by an excitation device via a first frequency band, and receives a control signal transmitted by the excitation device via a second frequency band, where the first frequency band is different from the second frequency band. The electronic tag demodulates the control signal from the second frequency band, and modulates, based on the control signal, description information describing a product to a reflected signal such that the reflected signal is modulated with the description information and has a same frequency band as the first frequency band. The electronic tag transmits the reflected signal to a receiver.
