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.

The invention relates to a pigment particle for security applications, comprising a duromer matrix and a plurality of core particles of a thermoplastic polymer with a feature substance dissolved in the core particles embedded therein, wherein the feature substance is an organic or metalorganic substance. The invention further relates to a method for producing security pigments, for example luminescent printing pigments, by means of incorporation into a duromer matrix of thermoplastic polymer particles in which the luminescent illuminant is present respectively in dissolved form.

Provided is a laminated body in which a print layer is provided downstream of a laser color development layer without lowering quality. A card is provided with an offset print layer laminated on a base material, a buffer layer laminated on the offset print layer and having translucency, and a laser color development layer laminated on the buffer layer. The buffer layer minimizes scratches on the offset print layer that occur with the heat generation of the laser color development layer.

The present invention refers to a safety device (1) for authorizing an operation, comprising: a supporting structure (2); a color-shift structure (5) coupled to the supporting structure (2) on a side or face of this latter; a first safety string (6) made in the supporting structure (2) and disposed on said side or face of the supporting structure (2) so that the first safety string (6) and color-shift structure (5) are overlapped on each other; a second safety string (7) made in the supporting structure (2) and disposed on said side or face of the supporting structure (2) so that the second safety string (7) and color-shift structure (5) are overlapped on each other. The present invention refers also to a safety method and system for authorizing an operation exploiting such safety device.
