Abstract
A resonance label (E) is deactivated by transmitting only a single discharge pulse which produces only a click signal instead of an oscillation and destroys the label (E). A discharge capacitor (C1) which is connected in series with a transmitting antenna (L1) and is rechargeable via a switching system (LDR, 1-5) preferably serves as the energy source for delivering the discharge pulse.
Claims21
A process for deactivating a resonance label in which the latter is excited by means of an energy-supplying transmitter without requiring contact between the resonance label and the transmitter, wherein a single discharge pulse, in the form of a click signal, is delivered via the transmitter.
