Information verifying assembly, has detector device including read head with stack of materials and board that is provided with strips, where stack is positioned between side of one of strips of board and printed side of support

摘要

The assembly has a support (12) i.e. book, formed of a paper sheet on which a series of information is printed, where the information is not identified by human visual perception. An autonomous detector device i.e. electronic detector (15), has a read head with a stack of parallel conducting and insulating materials (9) and a printed circuit board (1) that is provided with interlaced conducting strips in its lower part (6). The stack is positioned between a side of one of the strips of the board and a printed side of the support.
