The method also includes recording a transaction associating the first unique identifier and the second unique identifier with a predetermined amount of cryptocurrency in a recordation facility accessible for validation of the cryptocurrency.

Using software to process images and/or digital representations of paper currency to determine if currency has a value greater than the face value of the currency to any person or persons. Software that can determine from images and/or digital representations (known or unknown) numismatic value, or value greater than the face value of the currency to any person or persons and indicia of numismatic value, or increased value, including, but not limited to: ink smearing, misaligned serial numbers, misaligned seals on currency, non-matching serial numbers, off center printing, off-center cutting, paper currency of small or limited print runs, fancy serial numbers, missing or off-center watermarks, errors in security features, holograms, ultra-violet features, magnetic features, microprinting, etc. to determine a numismatic value.

An automated machine 1 is provided to comprise a communications device 5 for receiving remotely operable signals emitted from a mobile terminal 10 to produce monetary signals corresponding to money amount data in the remotely operable signals, a bill acceptor 4 for validating bills inserted from the outside to produce the monetary signals when bill acceptor 4 judges the inserted bill to be genuine and for relaying the monetary signals from communications device 5, a control device 8 that has built-in program software to produce drive signals of the amount corresponding to the monetary signals in accordance with the program software when control device 8 receives the monetary signals from bill acceptor 4. In another aspect, communications device 5 may receive the remotely operable signals emitted from mobile terminal 10 to produce the monetary signals corresponding to the money amount data in the remotely operable signals and receive the monetary signals from bill acceptor 4 and send them to control device 8.

Disclosed are methods and systems that include obtaining at least one image of a dendritic structure, analyzing the at least one image to identify one or more features associated with the dendritic structure, and determining a numerical value associated with the dendritic structure based on the one or more features.

Provided is an information display medium that can enhance a forgery prevention effect. An information display medium (100) includes a light reflection layer (20) made of a metal or a metallic oxide and partially or fully placed on one surface of a substrate, and the light reflection layer (20) includes a first region (30) where first information is displayed by either of or a combination of an outline shape and a shape of an uneven region, and a second information display region (21a) where identification information formed by partial material removal of the light reflection layer (20), the second information display region being set to partially or fully overlap with the light reflection layer (20) where the first information is displayed in the first region (30).

A security device includes a substrate and a photoluminescent image on or in the substrate. The image includes at least two different visible light emitting photoluminescent quantum dot compositions, each arranged according to different respective photoluminescent sub-images. The at least two different visible light emitting photoluminescent quantum dot compositions have different emission spectra from one another, and the same or different excitation spectra. The at least two different visible light emitting photoluminescent quantum dot compositions emit different respective visible colours from one another when excited. The respective photoluminescent sub-images are configured such that the photoluminescent image formed by the combination of the respective photoluminescent sub-images is multi-coloured, emitting different visible colours in different laterally offset parts thereof upon excitation of the at least two different visible light emitting photoluminescent quantum dot compositions. At least a portion of the photoluminescent image overlaps an at least semi-transparent region of the substrate.

The invention provides a security document having a transparent window, the security document comprising: a transparent polymeric substrate; an infrared-absorbent composition coated on or incorporated within the substrate at the window, the infrared-absorbent composition comprising particles of doped or Magnéli phase tungsten oxide.

A banknote monitoring apparatus includes a reception section that receives information including a serial number from each of a plurality of banknote processing apparatuses processing a banknote with the serial number; and a control section that determines whether a specification of the banknote has been changed based on an identification rate of the serial number obtainable with the information received.

A method of detecting a counterfeit item using a contactless scanner includes contactlessly scanning at least a portion of an item to generate a scanned image of the at least a portion of the item, wherein the at least a portion of the item comprises a graphic, identifying elements in the scanned image that correspond to elements in the graphic, measuring the identified elements to generate a plurality of element measurements, determining whether the item is counterfeit based on a comparison between at least one element measurement of the plurality of element measurements and at least one reference element measurement that is associated with an authentic version of the item, and in response to determining that the item is counterfeit, generating an alert indicating a detection of a counterfeit item.
