Abstract
Provided are an RFID tag information reading apparatus and method, including a signal management circuit, configured to output an operation frequency signal; a resonant circuit, configured to receive the operation frequency signal, adjust a capacitance value and an inductance value of the resonant circuit according to the operation frequency signal, so that the resonant circuit generates a resonance for generating a sine wave signal at a frequency point of the operation frequency signal, the resonant circuit is further configured to generate an electromagnetic wave from the sine wave signal, radiate the electromagnetic wave to a tag, and trigger the tag to return a tag identity signal; and a decoding identification circuit, configured to identify tag information according to the tag identity signal returned by the tag; where the signal management circuit is connected with the resonant circuit, and the resonant circuit is connected with the decoding identification circuit.
