Abstract: Methods and systems for generating a secure copy of content associated with a non-fungible token (NFT) are disclosed. The system will receive a print request to print digital content that is associated with an NFT, access a blockchain to identify a current owner of the NFT, and generate a print job that with instructions to print the NFT content. If and only if the current owner of the NFT is the requesting entity, the system will print a unique authentication code with the digital content. The system will cause a print engine to print the digital content on a substrate or as a 3D object. In some embodiments, the system may be included in a print device that includes the print engine. Other aspects include a system that verifies whether a printed copy of content is an authorized copy, using the unique authentication code and the NFT described above.

Abstract: Apparatus (10) for dispensing a potable beverage (B) stored in a container (K). A tap (16) is attached to the container and provides a discharge passage (18) for the beverage. A valve (20) opens and close the passage. A valve control unit (32) operates the valve. The container is a pressurized container and the valve control unit also utilizes this source (G) of pressure to operate the valve. A controller (60) activates the valve control unit. The controller includes a sensor (64) for first sensing when a receptacle is positioned adjacent the tap, to activate the valve control unit, for beverage to be dispensed into the receptacle. The controller subsequently senses when the receptacle has been withdrawn to deactivate the valve control unit and stop dispensing of the beverage. Dispensing is also automatically stopped if the receptacle is left in place for a preselected amount of time. The apparatus is available in a "kit" form for retrofitting existing dispensers.
