摘要:
A banknote acceptor for authenticating a banknote 2, has a sensing station S with detector 18 that produces image signals corresponding to a face the banknote. A processor 24 pre-processes the image signals and compares them with stored reference data corresponding to an acceptable banknote from memory 25 to determining the authenticity of the banknote and its denomination. A display device 29 displays an image 31 corresponding to the banknote under test based on the image signals from the detector 18, to allow the user to perform a visual check that the banknote detected at the sensing station corresponds to the banknote under test presented by the user. Also, the detected denomination of the banknote is displayed on device 32. The user can accept or reject the banknote using buttons 33 and 34, and retrieve images of previously accepted banknotes with button 35.

The present invention relates to a production method and to a device for document security applications including various latent images on each side. The invention comprises: depositing, according to an established pattern, at least one layer of metallized material, forming a holographic element on at least one part of one of the surfaces of a confinement substrate; defining different regions on the surface of the substrate; inducing different alignment directions for orienting a liquid crystal according to the previously defined regions; doping the liquid crystal with at least one dichroic dye; placing the liquid crystal over at least one confinement substrate, covering the holographic element; adding a second confinement substrate, forming a sandwich-type structure; and polymerizing the liquid crystal, forming a sheet.

A secure and/or valuable document, such as a banknote (1), incorporates verification means (11;21;31;41) for verifying a security feature (10;22;32;43) on the same or a different security document when the verification means and the security feature are laid over one another. Examples of verification means comprise optical lenses (11), graphic elements, optical filters (21;31), interference filters or line or dot grids (41). An optical filter may take the form of a colour tinted filter (21) for viewing a security element (22) comprising area printed with metameric inks on the same or a different security document. Another form of optical filter is a first transparent polarising window (31) for verifying a second transparent polarising window (32) on the same or a different security document.

The present invention relates to a circulation-type banknote/check deposit/withdrawal apparatus using a lateral deposit/withdrawal scheme and a method of handling banknotes and checks applied thereto, and more particularly, to a circulation-type banknote/check deposit/withdrawal apparatus using a lateral deposit/withdrawal scheme and a method of handling banknotes and checks applied thereto, wherein banknotes and checks of various sizes can be deposited and withdrawn through a single deposit/withdrawal unit; a carrying path is configured to carry the banknotes and checks deposited through the deposit/withdrawal unit in a lateral direction; and the carrying path is provided thereon with a medium alignment unit for aligning the carrying position on the carrying path of the banknotes and checks being carried thereon, so that the banknotes and checks, which have been deposited through the deposit/withdrawal unit and are being carried in the lateral direction, can be carried in a state where the banknotes and checks are aligned with a predetermined alignment position on the carrying path by the medium alignment unit, and stacked into respective corresponding cassettes, thereby optimizing the sizes of check and banknote cassettes based on the sizes of corresponding media (banknotes and checks), enhancing the carrying efficiency of the media on the carrying path by using the lateral deposit scheme, and increasing the processing speed of the media while reducing the volume of the deposit/withdrawal apparatus.

A portable hand-held device for use in authenticating documents includes a camera for capturing images from the document to be authenticated as well as on-board computer-implemented instructions to capture and analyze Digitally Watermarked images and output an indication as to whether the document is authentic or not authentic.
摘要:
The invention relates to a method and an arrangement for verifying a security document having a security feature in the form of at least one pigment-like conversion phosphor which can be excited in a first wavelength range of electromagnetic radiation to emit electromagnetic radiation in a second wavelength range, wherein the first and the second wavelength ranges lie in the visible spectral range. The arrangement comprises a freely programmable mobile telephone having a light source for irradiating a check region of the security document with visible light in a first wavelength range and have a photosensor for picking up visible light. The mobile telephone is configured to compare the radiation emitted by the conversion phosphor in the second wavelength range and picked up by the photosensor with predefined data and to signal correspondence.
