What it may cost

There is no single fixed charge for a declined tap. If a boarding or exit was not recorded correctly, staff may need to check the journey before you pay again.

How to avoid it next time

  • Keep only one contactless transit card near the reader.
  • Check the balance before a longer journey.
  • Wait for the confirmation sound or screen before moving the card.
