A physical card (in some cases without any on-board source of power or computing capabilities) is configured to maintain access information for digital bearer assets. The physical card may include disposed thereon a single address operable to receive digital bearer assets in one or more transactions on a decentralized computing platform, like a blockchain-based decentralized computing platform. Other decentralized computing platforms utilize different address generation protocols, thus preventing use of a single address on those other platforms. A set of addresses is generated, each address corresponding to a given decentralized computing platform. Each address is based on a same underlying key-pair, and a primary address is selected from the set for a given card. The remaining addresses in the set are stored, without storage of the public key or private key, and returned in a response to a request for additional addresses of the currency card.

A method for marking a product (1) with a photoluminescent mark, said mark comprising a photoluminescent portion (10) which is transparent under normal light conditions and revealed by photoluminescence under UV illumination, said mark further comprising a non photoluminescent portion (9) which is transparent under normal light conditions as well s under UV illumination, said method comprising: deposing on said product a stack, said stack comprising alternatively layers (2,4) such as AIN, with a thickness of less than 1 micron and layers (3) of a second material, such as GaN with a thickness of less than 10 nm; raising the transparency of said non photoluminescent portion (10) with a deposition of transparent material (6) or incorporation of ions into said non photoluminescent portions.

A card for distributing advertising and information is described. The card, which can be laminated, includes a card body and an expandable component that is detachable from the card body. The expandable component includes two connected plies of material that are connected to form a closed end that is opposite to a detachment end at which the expandable component is detachable from the card body. The expandable component optionally may include one or more sheets of material that are arranged in a folded configuration between the two plies while the expandable component is still attached to the card body. Once the expandable component is detached from the card body, the expandable component is openable to reveal concealed printed matter printed on an interior surface.

Among other things, one or more systems and/or techniques for labeling a refill contain and/or for enabling operation of the refill container by a dispensing system based upon one or more indicia of the label satisfying a dispensing key are provided. In an example, a label may be applied to a refill container. The label may comprise a first region having a first indicia that may correspond to a shape, color, and/or texture (e.g., a yellow star indicia). A dispensing system may enable operation of the refill container (e.g., installation and/or dispensing of material from the refill container) based upon the first indicia satisfying a dispensing key (e.g., a yellow key component and/or a star shape component). Otherwise, the dispensing system does not enable operation of the refill container (e.g., the refill container is not genuine or is not an appropriate refill container type).

Labels for food, beverage, cosmetic, pharmaceutical, nutraceutical, reagent, or vitamin packaging articles are provided. The labels include a print that is initially hidden, but at a later time period the print or an image within the print becomes visible to the consumer. The print or the image can, for example, include the expiration date of the product. A food, beverage, cosmetic pharmaceutical, nutraceutical, reagent, or vitamin packaging articles is also provided that includes a reservoir having a dye. Upon expiration of the product, the dye is released to taint the product so that a consumer has notice to avoid using the product.

The present invention relates to a web authentication hologram label and a method for manufacturing the same, and more particularly, to a web authentication hologram label and a method for manufacturing the same which in forming a web authentication label for identifying a genuine article, enable enhancement of a forgery (and falsification) preventing function as well as duplicate authentication for confirming whether or not an article is genuine to be substantially impossible by means of adopting one-time authentication.

Disclosed are a label film including a hidden pattern that is displayable through scraping a surface thereof and a manufacturing method thereof. A concealment scraping layer printing ink is formed by mixing, in respect of volume ratio, 1-10% nitrocellulose, 5-15% polyamide resin, 20-30% silver paste, 5-15% pearl powder, 10-20% ethyl acetate, 20-30% toluene, and 5-15% isopropyl alcohol and applied with intaglio printing such that a displayable mark formed of a traditional printing ink and including at least one pattern, character, or mark and at least one concealment scraping layer pattern formed with the concealment scraping layer printing ink are combined together and collectively formed on and attached to at least one surface of a single-layer label film substrate, with the concealment scraping layer pattern set on and covering at least one displayable mark, followed by steps of slitting, bonding, and cutting, to form a label film having at least one concealment scraping layer pattern covering and concealing at least one displayable mark through a combined printing operation.
