Abstract
An apparatus and method are provided for product verification wherein a verification marker attached to the product produces a signal identified by a disguised scanning code and matched to a visible code indicia on the product. The signal from the marker is in response to a known applied interrogation field generated by a scanning unit. The scanning unit is portable and includes a detector for the response signal. An EPROM processes the response signal and generates the scanning code. The programming is such that the code is random and different for each manufacturer/product and corresponds to the visible code indicia. The marker includes an amorphous metal ribbon having a known magnetomechanical vibration characteristic.
