This means that a previous payment from your presented card or device was declined by your card issuer, and so we have had to temporarily prevent your card/device from being used for travel on our services (payment is requested after travel).
Tapping a blocked card/device will trigger an attempt to retry any declined fares. If successful, your card/device will be unblocked, which usually takes up to 30 minutes and may result in a pending payment. This is not payment for that journey – it is an attempt to retry declined fares.
You can check the status of your card by logging into our contactless portal, or by contacting our Product Support team.
