Weighted transaction cards and methods of manufacturing the same. The weighted transaction cards may include a tungsten member that comprises at least a portion of a layer of the transaction card. The tungsten member may be encapsulated and/or disposed in an opening of a surround to define an inlay. The inlay may be laminated with one or more additional layers according to traditional card manufacturing techniques (e.g., a hot lamination process). The weighted transaction cards may have a weight significantly greater than traditional plastic transaction cards.

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.

A transaction card construction and a method for making transaction cards provides increased security for transaction card magnetic strips. The transaction card construction includes a card inlay and a clear card body. The card inlay is formed via a lamination press process with the magnetic strip attached to a back surface of the card inlay. The card body may have a window through which a data storage element may be exposed for accessing, such as by a magnetic stripe reader or EMV chip reader. The card body may be formed by adhering the card inlay to the clear card body.

Provided is a contactless-type metal card with an electromagnetic wave absorption sheet. The contactless-type metal card may include: a metal body sheet made of a metal material; an antenna inlay sheet made of a synthetic resin material with an antenna mounted on one side thereof; an electromagnetic wave absorption sheet disposed between the metal body sheet and the antenna inlay sheet; an IC device for card mounted on the metal body sheet or the antenna inlay sheet and having terminals connected to two ends of the antenna; a first thermal adhesive sheet disposed between the metal body sheet and the electromagnetic wave absorption sheet; and a second thermal adhesive sheet disposed between the electromagnetic wave absorption sheet and the antenna inlay sheet. The electromagnetic wave absorption sheet is preferably formed by mixing a powder of materials having a property of absorbing an electromagnetic wave and a binder.

Cards made in accordance with the invention include a specially treated thin decorative layer attached to a thick core layer of metal or ceramic material, where the thin decorative layer is designed to provide selected color(s) and/or selected texture(s) to a surface of the metal cards. Decorative layers for use in practicing the invention include: (a) an anodized metal layer; or (b) a layer of material derived from plant or animal matter (e.g., wood, leather); or (c) an assortment of aggregate binder material (e.g., cement, mortar, epoxies) mixed with laser reactive materials (e.g., finely divided carbon); or (d) a ceramic layer; and (e) a layer of crystal fabric material. The cards may be dual interface smart cards which can be read in a contactless manner and/or via contacts.
