ABSTRACT:
A method and device for activation of large quantities of security elements for the electronic article protection. The security elements are exposed to at lease one magnetic field produced by one or more coils carrying a line current subjected to sine oscillations. The coils are supplied with current pulses that are shorter than the sine oscillations. The amplitude of the current pulses diminishes as a function of time.
