Abstract: An information carrier medium includes at least first and second sheet members (12, 14) each having first and second surfaces opposite to each other and laminated together with the first surface of the first sheet member bonded to the first surface of the second sheet member. A security indicium (14; 71) is formed on at least one of the first surfaces of the respective first and second sheet members (12, 14). The security indicium is made of at least one inking material of a kind capable of responding to a coherent light when irradiated thereby. An electro-optical reader for reading the security indicium (14; 71) is also disclosed.

Abstract: A highly efficient manufacture of magnetic cards can be achieved by the arrangement of the present invention in simple and compact structure. The manufacturing apparatus including laminating and cutting devices can automatize every step required for manufacture, e.g., supply, transfer and positioning of material or discharge of a finished card. In other words, the manufacturing arrangement performs the total process automatically from pre-treatment to post-treatment with high efficiency.
