  • Apparatus for authenticating products and authorizing processes using the magnetic properties of a marker
    Patent number: 6498864
    Abstract: The authenticity of an item which is one of a group of such items can be determined by attaching to or incorporating into each such item an authentication marker, all such markers interacting substantially identically with a given magnetic field. A field generating apparatus is provided which incorporates a reference sample that interacts with the given magnetic field in the same way as the authentication markers do. The field generating apparatus subjects both the reference sample and a candidate authentication marker to substantially identical magnetic search fields.
