Among Us was released in 2018 by the American studio Innersloth and found mass popularity in 2020 through streamers and social clips. The Medbay scan is one of its visual tasks, which only crewmates can complete, so watching a player scan became trusted proof they were not the Impostor when visual tasks were enabled. That reputation travelled beyond the game into edits and memes, where the long scanning sound now signals anyone or anything being verified as genuine, safe or completely innocent.
