To verify that a fare has been paid, the transit enforcement officer will typically ask you to tap your card on an enforcement card reader in order to verify paid fare status on their database. The enforcement card reader will check the transit authority database and if there is no record of payment or an attempt to pay, you may be issued an offence ticket. If the original payment was declined by the bank, you may be asked to pay your fare. If the enforcement card reader loses connectivity when verifying your payment status, you will be permitted to continue to travel and the system will check once connectivity is re-established. If the system confirms your fare was not paid or a payment attempt was not made, an amount up to the maximum fare for the transit authority may be charged against your account.
