A method for manufacturing a portable data carrier by means of a continuous manufacturing method, comprises the steps: providing at least one foil as a rolled good, unrolling at least one first foil, with at least a first foil being coated at least partly with an adhesive on at least one side, with at least the first foil being scored on at least one side along at least one creasing edge, with at least the first foil being folded up in precise fit along at least one creasing edge and bonded, with the foil being folded up in the direction of the side which is coated with adhesive, with the side coated with adhesive being arranged on the opposite side of the foil which has at least one scored creasing edge along which it is folded.

An individual certificate medium includes an optical security patch in which a relief layer and a metal layer include a first area and a second area. The first area includes an altered region and a portion of the relief layer overlapping with the altered region as viewed in the thickness direction of a recording layer. The second area includes a non-altered region and another portion of the relief layer overlapping with the non-altered region as viewed in the thickness direction. As viewed in the thickness direction, the first area transmits light incident thereon, while the second area absorbs light incident thereon to hide a recording region. In a direction intersecting the thickness direction, the first and second areas cause light incident on the optical security patch to emerge as diffracted light.

Provided are: a light diffraction layer laminated sheet which enables easy production of a card that has a light analysis structure; and a card. A light diffraction layer laminated sheet material which forms a part of a laminated structure of a card by being laminated on top of a card base material. This light diffraction layer laminated sheet material is provided with: a transparent sheet layer; a hologram layer that has a contour smaller than the contour of the transparent sheet layer and is laminated on one surface, which is the upper surface, of the transparent sheet layer; and an HS layer that bonds the transparent sheet layer and the hologram layer with each other.

The present invention relates to a web authentication hologram label and a method for manufacturing the same, and more particularly, to a web authentication hologram label and a method for manufacturing the same which in forming a web authentication label for identifying a genuine article, enable enhancement of a forgery (and falsification) preventing function as well as duplicate authentication for confirming whether or not an article is genuine to be substantially impossible by means of adopting one-time authentication.
