- "I need you to keep him alive to deliver the datacard to the rendezvous in person."
- ―Han Solo, detailing Beilert Valance's job of escorting Vharn

A datacard, data disk, or datadisc was a flat, handheld device used to store information. Chain codes were often stored in these devices.
During the Battle of Scarif, the Death Star plans stolen by Rogue One were beamed to the Profundity, where they were transferred to a datacard. The card was given to Princess Leia Organa,[2] who later tried to deliver the plans to Obi-Wan Kenobi on Tatooine. When her ship fell under attack from the Imperial I-class Star Destroyer Devastator, she stored the datacard into the memory banks of R2-D2, shortly after recording a message for Kenobi.[3]
Behind the scenes
Datacards feature as an in-game resource, containing characters and other materials, in the non-canon video game Star Wars: Galaxy of Heroes, ranging from bronzium to packs of chromium and the most expensive aurodium.
