? Card is a consumable in The Binding of Isaac, added in the Afterbirth DLC.

Activates Isaac's active item without wasting a charge, or making one-time-use items disappear.

Does not work for active items that are in the consumables slot.

When used with Blank Card, it will teleport Isaac to the I AM ERROR room, consuming both Blank Card and the ? Card in the process.
