Abstract
An identification document includes a first surface, at least a portion of the first surface being made of foamable synthetic material, and a tactile relief marking having a bubble structure formed in the foamable synthetic material. A method is used for producing at least one tactile relief marking on an identification document by an irradiation source. The identification document includes a surface having foamable synthetic material that has a property of increasing its volume by foaming upon application of energy. The method includes selectively irradiating the foamable synthetic material with energy to cause the foamable synthetic material to foam, thereby forming a tactile relief marking

An identification document, comprising:
- a first surface, at least a portion of the first surface being made of foamable synthetic material, and
- a tactile relief marking having a bubble structure formed in the foamable synthetic material.
A method for producing at least one tactile relief marking on an identification document by an irradiation source, the identification document including a surface having foamable synthetic material that has a property of increasing its volume by foaming upon application of energy, comprising:
- selectively irradiating a first surface of the foamable synthetic material with energy from the irradiation source to cause the foamable synthetic material to foam, thereby forming a tactile relief marking on the first surface.
