This disclosure enables various technologies for augmented-reality, which allow a person to obtain (e.g., electronically reserve, electronically purchase, physically receive) a memorabilia item during an event at or remote from a venue in which a performer is performing or within a preset time period after the event (e.g., within few hours after the event) at or remote from the venue. These technologies may reduce a rise in counterfeits of the memorabilia item, while minimizing a price increase of the memorabilia item.
