Data Carddass make use of special Carddass cards with data stored on them. These collectible cards can be read by various Data Carddass machines in order to interact with the game.

Depending on the machine, cards can either be inserted via a slot or scanned via a flat panel. Each machine is also fitted with various controls unique to their specific minigames, such as buttons which require timed presses or touches.
