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 label is provided with a warning layer coating integrated or applied to a front side of the label. The warning layer coating is not activated by application of heat; rather, the warning layer coating activates upon a directional force (vertical or horizontal pulling) applied to the label after the label was initially adhered to a container, bag, box, and/or object. Upon activation, visible color or a printed warning indicia is visible on a front surface of the label, providing evidence that the label was removed after initial application or providing evidence that the label was attempted to be removed after initial application.

A sealing device for sealing at least one storage and/or packaging device for durable goods, particularly machine tools, and/or for sealing at least one piece of information includes at least one information carrier unit for receiving the at least one piece of information and/or a security key, particularly durable-goods-specific information and/or a durable-goods-specific security key. The sealing device also includes at least one fastening unit, particularly an adhesive unit for fastening at least the information carrier unit to the storage and/or packaging device or to the durable goods, particularly machine tools. The sealing device further includes at least one sealing unit for an at least substantially irreversible visualisation, for the first time, of the information carrier unit and/or a first-time opening of the storage and/or packaging unit. The sealing unit covers at least the information carrier unit in the at least one sealing state such that it cannot be seen.

A label having an imprint layer, a non-opaque layer, and a carrier layer is described. The label allows for printed information to be fixed to the outward-facing imprint layer. It is then removed from the carrier layer and applied to a curved surface so as to wrap completely around the object and overlap and adhere to itself over however many revolutions may be required. The trailing edge of this label can be selectively and non-destructively peeled away, and unwound to reveal the entire length of label and the printed content thereon, with its adhesive still being sufficient to allow the label to be rewound.

An instance of a physical product includes a verification code and a unique identifier disposed thereupon by which authenticity or condition of the instance may be determined. The combination may be uniquely associated with the instance and stored, by the issuer or manufacturer for each authentic instance, locally or within a decentralized computing system having an immutable data store. The verification code may be concealed by a tamper-evident component such that access of the verification code is evident upon visual inspection. Verification may require revealing of the verification code with tamper-evidence and submission of a request including the verification code and the unique identifier (or representation thereof) to receive a verification result. Each request to verify an instance may be recorded and returned with a next request for verification of the same instance of the product to indicate whether another entity has already performed a verification.

The present application is directed to a rotating shrink label measurement systems for a container and methods thereof. A base label may be adhered to the container, and measurement information displayed on the base label. A top label may cover at least a portion of the base label. The top label may be rotatable about the base label to a specific unit of measurement. The top label may have a transparent window allowing measurement information for the specific unit of measurement to be visible through the transparent window. The container and top label may be enclosed by a tamper evident sleeve.

A label sticker includes a release layer strip, an attachment layer strip and a label layer strip. The attachment layer strip is made of an artificial dressing material and its lower surface is coated with or adhered to a first glue layer. The lower surface of the attachment layer strip is attached to the upper surface of the release layer strip through the first glue layer. The label layer strip is made of a waterproof material and its lower surface is coated with or adhered to a second glue layer. The lower surface of the label layer strip is attached to the upper surface of the attachment layer strip through the second glue layer. The label sticker, to be adhered to the human skin to serve identification purposes, can be manufactured by mass production but is unlikely to be wetted and smeared.

A visual-information security system that includes an information security label positioned to conceal visual information on a substrate. The information security label may include a spiral-shaped cut (or other complex shape) within the body of the label and a pull-tab, such that when a user pulls on the tab, the label peels off of the substrate in a spiral pattern, revealing the information concealed beneath the label. The complex-shaped cut makes reapplication of the label difficult and evident, thus providing security to consumers. The label may include multiple layers of material, for example, a peel-off layer and an adhesive layer.

A method of making a container having a tamper evident feature. The method comprises affixing a tamper evident tag to a bottom end so that the tag covers perforations in the bottom end. The tag may be a film-based tag incorporating a color shifting ink layer. When the container is opened, air enters the interior of the container, passes through the perforations and activates the color shifting ink layer.

A physical currency card (in some cases without any on-board source of power or computing capabilities) is configured to maintain access information for digital bearer assets. Public access information, like a cryptographic hash address operable to receive digital bearer assets or a public key operable to derive a cryptographic hash address operable to receive digital bearer access, may be visible upon inspection of the card such digital bearer assets may be transferred to the card in one or more transactions on a decentralized computing platform, like a blockchain-based decentralized computing platform. Private access information, like a secret, private key that corresponds to the public key (e.g., a public-private key-pair) or a representation of the private key (like a ciphertext thereof) and corresponding encryption key, is physically concealed with tamper-evident components such that a user can readily determine whether the private access information was divulged.
