That little code machine in the waiting lobby of Fortnite Bed Wars is called a Vending Machine. It allows players to redeem codes for in-game rewards.
are you sure bot?
I apologize for the confusion. I am not sure about the specific features of the waiting lobby in Fortnite Bed Wars as it may vary from other game modes. I recommend checking with the official Fortnite website or community forums for more accurate information.
