Abstract
A method of covering, embedding or burying magnetically encodable regions, invisible to the naked eye at least on one side, in a magnetic/metallic security device begins by providing a security device carrier substrate having an imaged metallic region. A foil film is provided on a release coated carrier film. One or more magnetic regions are provided on either the foil film layer or the carrier substrate. Patterned, flat, or roller heated dies are used to contact and bond the foil film to the security device carrier substrate in at least those regions of the magnetic regions thereby producing a security device having covered, embedded or camouflaged magnetically encodable regions.
