Abstract
The present disclosure provides an anti-removal monitoring circuitry, applied to an electronic tag. The circuitry includes a first input terminal, a second input terminal and an output terminal. The circuitry further includes: a shutdown circuit, configured to control the electronic tag to be in a shutdown state in response to connection between the first input terminal and the second input terminal; and a starting-up circuit, configured to control the output terminal to output a pulse voltage signal in response to disconnection between the first input terminal and the second input terminal, in such a manner that the electronic tag generates an alarm signal in response to the pulse voltage signal.
