 Like their physical counterparts, Steam Trading Cards are a collectible commodity which are routinely traded, bought, and sold.Supported games each have their own set of trading cards, which typically incorporate game art in their designs.After collecting a full set of trading cards, the user has the option to "craft" the cards, permanently removing them from their Steam inventory in exchange for a game-themed emoticon, profile background, profile badge, and an amount of Steam "XP".
