CARD EQUIPPED WITH BAR CODE

摘要

PURPOSE:To make it impossible to read a code from the outside in the case of a magnetic bar code though reading can be performed irrespective of an insertion direction of a card or the like. CONSTITUTION:Two bar codes 2, 3 of same content to be read out in the opposite directions are provided at positions in line symmetry or point symmetry to a center line C in the read direction on a same face. In the case of a magnetic bar code, a non-magnetic material bar layer having the same form and the same thickness as the magnetic material bar layer is formed at a read point having no magnetic material bar layer.
