A method of authenticating and/or identifying a security article including a first image includes superimposing at least partially the first image of the article with a second image. The second image may be produced by an electronic imager. The method further includes performing a relative movement between the first and second images so as to make it possible to observe an item of information relating to authentication and/or identification of the security article during the relative movement between the first and second images.

A data carrier with a cover layer, a base layer, and an information layer arrangement. The information layer arrangement includes at least a first information layer and a second information layer arranged after the first information layer along an extension direction. The first information layer and the second information layer have different optical properties, and the information layer arrangement has an unmodified region and at least one modified region, the at least one modified region having at least one recess extending at least partially into the first information layer along the extension direction. The at least one modified region is configured to reflect incident electromagnetic waves whereby a first reflection spectrum is generated, the unmodified region is configured to reflect said incident electromagnetic waves whereby a second reflection spectrum is generated, the first reflection spectrum being different from the second reflection spectrum.

A secure multi-layered structure (14), for example, for a secure document, the secure multi-layered structure comprising a first layer (20) having a first aperture (25) opened in the first layer, a second layer (30) having a second aperture (35) opened in the second layer, and a third layer (40) having a third aperture (45) opened in the third layer, wherein each layer at least partially overlaps with the layer adjacent to it, at least a portion of the third layer being visible through the first aperture.

Aspects described herein may allow for a payment card assembly including a payment card having a first surface, an opposed second surface, and an aperture extending through the payment card from the first surface to the second surface. An insert may be removably received in the aperture. Each of a plurality of identification elements may be configured to be removably received in the aperture and have an identification characteristic different than an identification characteristic of each of the other identification elements.

A transaction card includes at least one metal layer having one or more apertures therein. A light guide is disposed beneath the metal layer. The light guide has a light output and a light input. The light output is positioned to transmit light through at least the one or more apertures of the metal layer. At least one LED is positioned to transmit light into the light guide light input.
