けることにより、カードの悪用を防止してきた。For example, as a means to prevent misuse, cards are made to hold identification information in advance, and there are invisible information that cannot be visually identified, and visible information that is visible but difficult to copy, forge, falsify, or number. The former includes a method of multilayering the magnetic recording layer, a method of hiding the magnetic recording layer with a magnetic shielding layer, or a method of providing invisible identification information on or in the card that can be detected optically, electrically, or magnetically. There is a method of determining this using a sensor. The latter includes methods of embedding, engraving, and transferring facial photographs, methods of complicating patterns by special printing using fine/precision printing, and fluorescent printing, methods of applying special processing such as holograms, and methods of applying warp to the magnetic recording layer.
Misuse of cards has been prevented by providing identification information on the cards, such as by providing marks.
