An optically variable surface pattern is made available, having at least two partial areas with reflection elements, wherein the reflection elements of the first partial region on the one hand and the reflection elements of the second partial region on the other hand reflect impinging light in different reflection directions. The first partial region is so covered with a first glazing ink layer that a viewer, upon a change of the viewing angle at which the viewer views the optically variable surface pattern, sees the first partial region glow in a first color upon reaching a first viewing angle. The second partial region glows in a second color that is different from the first color upon reaching a second viewing angle.

An apparatus for the calibration of a sensor system has at least one sensor and at least one excitation source, a control device for controlling the sensor system, a calibration medium and a drive which moves the calibration medium into an optical path of the sensor system in a calibration mode and moves the calibration medium out of the optical path of the sensor system in an operating mode for the testing of measuring objects. The calibration medium has more than one reference, where the drive moves the calibration medium into the optical path of the sensor system so that one of the references covers a detection area of the sensor system, and the sensor system measures the reference located in the detection area.
The invention relates to a method for performing machine checking of electronically-stored personal data in a passport booklet. The data are transmitted in an obscured form to a reader device after the passport has been presented to this reader device, and the accuracy of the obscuring is first verified and the obscuring is then removed. A positive signal is issued in the event of a successful verification. The recovered personal data are subsequently checked for authenticity. The verification and removal of the obscuring, as well as the authenticity check, ensue in a time-staggered manner after the passport booklet has been removed from the reader device by a verifying person in order to conduct further checks.

The invention relates to a value document, in particular a bank note, having a value document substrate and different feature substances for checking the value document. According to the invention, a first feature substance is incorporated into the volume of the substrate of the value document, and second and third feature substances are applied to the value document substrate in a printing ink jointly and in the form of a coding. The second feature substance is formed by a luminescent substance, and the third feature substance by a material absorbent in a special spectral range. The two substances are used for the value recognition of different user groups.

The invention relates to an apparatus as well as a method for reliably determining the deliberate use of a contactless data carrier. Beside an antenna-based data transmission channel in dependence on the data to be transmitted additionally an optical data transmission channel between reading device and data carrier can be employed.
