Tapping on and tapping off

  1. Have your card or device ready before you board:
    Take your card or device out of your wallet or bag to avoid card clash and make sure it can be read easily.
  1. Tap on with your card or device:
    Hold your card or device to the middle of the card reader and wait for a large white tick to appear on the screen, accompanied by a single beep.

    If you see a large white cross with red lights and hear a double beep sound, your tap was declined. If the screen says “Please try again”, make sure your card or device is separated from other payment methods and try tapping and again. More about error messages is provided below.
  1. Tap off just like you tapped on:
    When you successfully tap off, you’ll see a large white tick with green lights.
Listen to the successful tap sound:

Avoid card clash

  • Always present your payment method individually.
  • Card readers can read contactless credit and debit cards and smart devices.
  • Presenting multiple payment methods at once, like a phone with a card stored in the case or tapping your wallet with multiple cards, may cause your tap to be declined or result in a default fare.

Using smart devices and digital wallets

  • Your virtual cards and physical cards are treated as separate payment methods. To make sure you pay the right fare, always tap on and tap off with the same card or device.
  • For example, if you tapped on with your smart watch, tap off with it too.
  • If you have multiple devices for one account, these can be used as separate payment methods for additional travellers.

Card declined and error messages

If your tap is declined, you will see one of these messages:

  • Please try again:
    This means there was an error with the machine and your tap was not accepted. Make sure your card or device is removed from any wallet or case and try tapping again.
    Please try again error message displayed on the screen with a large white X and red corner borders
  • Present one card:
    More than one card has been detected by the reader. Remove the card or device that you want to use from your wallet or bag and try tapping again.
    Present one card error message displayed on the screen with a large white X and red corner borders
  • Invalid card:
    Your card is invalid and cannot be used to tap on and tap off for travel. This could be because of insufficient funds on a previous trip, or because you have presented a card that is not accepted on the network.

  • Not accepted:
    Your card cannot be used for travel. This could be because it has been reported lost, stolen or has been blocked by your financial institution.

    Your card has expired and can no longer be used.
