Abstract
A method and apparatus for detecting the presence of magnetic ink within a package without opening the package or altering its contents. The method and apparatus detects items marked with magnetic ink, such as bank checks, in an unopened package independently of the item's location within the package and despite the presence of such magnetic clutter as staples and paper clips. The apparatus and method is designed to eliminate magnetic noise from the equipment itself and from the environment.
