When traveling outside the U.S., some card readers at unattended terminals (such as public transportation kiosks or gas pumps) will require a PIN. In these situations, enter the debit or credit card PIN assigned to your card. Some international self-service terminals do not accept U.S.-issued debit or credit cards and may display a message such as 'Transaction Canceled'. This is known to happen on French toll roads or automated fuel dispensers depending on location. In these cases, please locate an attended terminal to complete your transaction or plan for an alternative payment method, such as local currency.
