The balance on the card is displayed when the user enters the ticket gate this way. The minimum fare is needed on the card when entering the train system, which is not deducted at that time. The balance is also displayed whenever the card is inserted into ticket or fare adjustment machines. A travel record is stored on the card, and can be displayed or printed out at the same places where cards can be purchased and reloaded. On exit, the card is again scanned at a card reader. At this time the fare is deducted from the remaining balance from the card and the new balance is displayed.
