    摘要： An IR and/or UV machine-readable optical security device (e.g., micro-optic security thread) that is made up of at least one IR-absorbing component with a characteristic IR signature detectable at two or more IR-wavelengths, at least one UV-absorbing component with a characteristic UV signature detectable at two or more UV-wavelengths, at least one IR-absorbing component that absorbs IR light and emits light at a different invisible wavelength, at least one UV-absorbing component that absorbs UV light and emits light at a different invisible wavelength, or a combination thereof, is provided. The IR and UV machine-readable features do not interfere with the optical effects projected by the optical material.

    摘要： A security device is disclosed that has an image formed upon a substrate. The image has a first printed region and a second different printed region both printed with a same ink formulation of field alignable flakes. At least one of the printed regions has optically variable effects. One of the first and second printed regions at least partially surrounds the other. The second printed region is formed of thin parallel lines and the first printed region has substantially wider lines than are printed in the second printed region. The area density of the ink in a line in the first group of wider lines is greater than the area density of a line in the second group of narrower lines. A surprising effect of this image is that particles or flakes in the ink are field aligned so as to produce a visible kinematic dynamic effect visible in the first region and not visible in the second region when the image is tilted or rotated.

    摘要： A user device may cause light to be emitted at a security article by one or more light emission devices of the user device. The user device may obtain from a first set of one or more optical sensor devices of the user device first sensor data associated with the security article, and may obtain from a second set of one or more optical sensor devices of the user device second sensor data associated with the security article. The user device may determine, based on the first sensor data and the second sensor data, one or more characteristics of a security feature of the security article. The user device may determine, based on the one or more characteristics of the security feature, whether the security article is authentic. The user device may cause, based on determining whether the security article is authentic, one or more actions to be performed.

    摘要： The present disclosure relates to a micro-optic device for producing a magnified image, including: a first unitary structure on one side of a substrate, the first unitary structure including a first group of focusing elements and a first group of imagery elements, wherein one of the first group of focusing elements and the first group of imagery elements is recessed with respect to the other, wherein the device further includes at least a first coating of ink overprinted on the first unitary structure, to at least partially fill the recessed group of elements, and wherein a property of the ink provides a visual contrast in the magnified image.

    摘要： Methods and systems disclosed herein may communicate information, such as alerts and notifications, to a cardholder via a color-changing transaction card. In particular, the cardholder may configure one or more thresholds that establish when a transaction card may change colors. For instance, a transaction card may change colors at, or while approaching, a first threshold. The transaction card may change colors at, or while approaching, a second threshold. When the cardholder's balance goes below the thresholds, the transaction card may revert back to the lower threshold color or the original color of the transaction card. Using the techniques described herein a financial institution may convey information to a cardholder in a way that does not require the cardholder to digitally engage with the financial institution.

    摘要： A spectrally responsive transfer system, comprising a taggant system comprising taggants exhibiting spectral characteristics in response to at least one illumination; a spectral code associated with the spectral characteristics; a coded transfer film releasably supported on a carrier allowing one or more portions of the transfer film to be selectively transferred from the carrier to a substrate to form spectrally coded indicia on the substrate; the transfer film comprising a spectral ink layer incorporating the taggant system and releasably coupled to the carrier; the transfer film also incorporating a metal foil layer over the spectral ink layer such that the metal foil layer overlies the spectral ink layer and such that the metal foil layer underlies the at least one spectral ink layer when the one or more, selectively transferred portions of the transfer film are transferred from the carrier onto the substrate.
