摘要： In order to support the verification of a security document, the document is placed on a verification device having a touchscreen. A conductive structure embedded in the document is detected by the touchscreen and the position and orientation of a window in the document is calculated therefrom. The verification device then displays an image positioned and rotated to appear at the location of the window. The image may interact with the document to generate Moiré patterns, fluorescent images or animations.

摘要： The carrier for representing a monetary value as a means of payment comprises a substrate, a control unit mounted to the substrate, a value store for storing a carrier value of the carrier, and an interface circuit for electronic communication of an external device with the control unit. The control unit is adapted and structured to modify the value store upon receipt of a request through said interface circuit. A large number of such carriers is used in a payment infrastructure having a plurality of terminal devices that are able to communicate with the carriers through their interface circuits. The infrastructure further comprises a central server device. Values can be transferred to and/or from individual carriers by various methods. A number of measures are described to protect the carriers and the rest of the infrastructure from tampering.

摘要： A security device for verifying an authenticity of a security document comprises an at least partially transparent substrate with a first surface and a second surface. A first pattern is arranged on the first surface. This first pattern is derivable using a first seed pattern. A second pattern is arranged on said second surface. This second pattern is derivable using the first seed pattern and using a second seed pattern. Transmittances and reflectivities of the first and second patterns are selected such that in a reflection viewing mode, only the first seed pattern is visible. In a transmission viewing mode, however, only the second seed pattern is visible.

摘要： A security document includes a non-homogeneous region formed e.g. by a structure of bars that vary the document's thickness dielectric permittivity or electrical conductance. The structure is verified by placing the document on the capacitive touchscreen of a verification device. Then, the user moves a finger or pen along the structure, which gives rise to a varying capacitive signal in the verification device. The signal can then be analyzed for deriving information about the document.

摘要： A security device for verifying an authenticity of a security document comprises an at least partially transparent substrate with a first surface and a second surface. A first pattern is arranged on the first surface. A second pattern is arranged on said second surface. The first and the second pattern each comprise a plurality of pixels with at least three different gray levels visible from a macroscopic perspective. The first and second pattern cover only gray levels in a range between 20% black and 80% black, in particular between 35% black and 65% black. The first pattern is inverted with respect to the second pattern.

摘要： The carrier for representing a monetary value as a means of payment comprises a substrate, a control unit mounted to the substrate, a value store for storing a carrier value of the carrier. and an interface circuit for electronic communication of an external device with the control unit. The carrier further comprises an owner store for storing the current owner of the earner. the current owner can e.g. be displayed on a display device of the carrier, or it can be used for restricting certain privileged operations on the carrier to its current owner. A large number of such carriers is used in a payment infrastructure having a plurality of terminal devices that are able to communicate with the carriers through their interface circuits, The infrastructure further comprises a central server device, Values can be transferred to and/or from individual carriers by various methods. A number of measures are described to protect the carriers and the rest of the infrastructure horn tampering.

摘要： The carrier for representing a monetary value as a means of payment comprises a substrate, a control unit mounted to the substrate, a value store for storing a carrier value of the carrier, a display device for displaying a status of the carrier and an interface circuit for electronic communication of an external device with the control unit. Further, an authentication device is provide for verifying the authenticity of the status shown by the display device. The authentication device e.g. comprises an optically variable device, a diffractive structure, an at least partially transparent structure, a grating, a Fresnel-lens, an optical polarizer, or a periodic structure. It is e.g. overlaid with or can be brought to overlay with the display device. It makes tampering with the display device more difficult.

摘要： A security device for verifying an authenticity of a security document comprises an at least partially transparent multilayer substrate with a first surface and a second surface. A first pattern is arranged on the first surface. This first pattern is derivable using a first seed pattern. A second pattern is arranged on the second surface. This second pattern is derivable using a second seed pattern. The security device furthermore comprises a third pattern arranged between a first and a second substrate layer. The third pattern is derivable using an inversion of the first pattern, an inversion of the second pattern, and a non-inverted third seed pattern. Transmit lances and reflectivities of the patterns are selected such that in a reflection viewing mode, only the first or second seed pattern is visible, respectively. In a transmission viewing mode, only the third seed pattern is visible.
