A datacard or data disk was a flat shaped device used to transfer information. During the Battle of Scarif, the Death Star plans stolen by Rogue One were beamed to the Tantive IV, where they were transferred to a datacard. The card was given to Princess Leia Organa who later tried to deliver the plans to Obi-Wan Kenobi on Tatooine. When her ship fell under attack of 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.
