The printed elements (17) have a traveling effect which depends on the angle of vision and forms an authenticity feature.
The invention relates to a portable data carrier (1), to an authenticity feature and to a method using a deformable data carrier base (7) and an authenticity checking device (2a).
This process allows manufacturers to apply an authenticity feature to their products.
The invention relates to a value document having at least one authenticity feature in the form of a doped-matrix-lattice based luminescent substance.
The authenticity feature to be examined diffracts the beam of the illumination source and projects it on an evaluation unit in the device.
The second authentication feature is machine-and/or visually controllable and is not influenced by the first arrangement of the first authentication feature.
Said structure of the mark of authenticity is thus modified locally in such a way that the lettering inscribed by the personalisation process appears as a negative image when the mark of authenticity is luminescent.
The originality of the value marker is verified by examining the authenticity marker and subsequently the value marker is demonetized.
Said safety element also comprises at least a second part in which another authenticity characteristic is arranged.
According to said method, in a first step, a luminescent mark of authenticity is inserted into or applied to the card composite and in a second step, the mark of authenticity is personalised using a high-energy beam, (e.g. a laser beam).
The intensity and/or the wavelength of the beam is selected in such a way that the structure of the mark of authenticity is locally bleached.
The invention relates to a security element for protecting valuable objects having first and second authentication features.
Objects which are to be examined are provided with a value marker which comprises at least one authenticity marker and optionally other security markers.
In order to check authenticity, a carrier-frequency signal is transmitted to the circuit and an output signal representing an authenticating feature is emitted from said circuit in response to said input signal and detected.
When triggered interactively by an external magnetic field, the authentication mark (20) shows a change of image which can be recognised visually and/or mechanically.
The invention relates to a valuable document such as bonds, identification cards or the like, having at least one characteristic of authenticity in the form of a luminescent substance.
The invention relates to a printed valuable document comprising an authenticity mark in the form of at least two luminescent substances on the basis of host lattices that are doped with one or more ions.
The invention relates to a printed valuable document comprising at least one authenticity mark in the form of a luminescent substance on the basis of host lattices that are doped with one or more ions.
All PAMP Suisse bars also feature an individual serial number and the assayer’s mark as signs of authenticity.
The invention relates to a printed document having a value and comprising at least one authenticity feature in the form of a luminescent substance on the basis of a host lattice doped with at least one rare-earth metal.
