What happens if a Transport for London (TfL) Inspector wants to check my Barclaycard OnePulse for Oyster travel?
You have a legal obligation to offer up your Barclaycard OnePulse for inspection by Transport for London (TfL) and National Rail Revenue Protection Inspectors if you are using it on London’s transport network, even though the card belongs to Barclays. You should not surrender your Barclaycard as this is a credit card. When inspectors scan the card to check the Oyster products, they are not able to access the Visa payments applications at all – there is no chance of any personal data or payments information being read or corrupted by this process.
