You has to pay for

Credit and debit cards are accepted for the purchase of Reservation tickets and services at all staffed stations. Debit cards must have a credit card logo and will be processed as credit card transactions; cards that require the entry of a PIN (personal identification number) are not accepted. There is no minimum amount required for credit and debit card purchases.

The following rules govern the acceptance of credit and debit cards at Reservation ticket counters:

• We accept American Express, Discover®, MasterCard®, VISA, Universal Air Travel Plan, Diners Club, JCB or China Union Pay credit and debit cards at ticketing locations.
• Reservation ticket agents accept only valid, unexpired cards.
• The person whose name is embossed on the front must sign the card on the back of the card. Unsigned cards are not accepted. The signature on the back of the card must match the signature on the ticket or charge form.
• Credit and debit cards are accepted for the amount of the sale only and may not be used to obtain cash.
