Payment is by Card only. You will be prompted at point of sale during the checkout process before you order your Ride or Rail ticket to select your chosen payment card to make payment. You setup your payment card and any delegate cards for employees you are booking on behalf of in the 'Profile' tab under 'Payment Methods' in the app and Webapp. Alternatively you can 'Add a Payment Method' at checkout in the app only. Not in the Webapp so please setup the payment card before starting a booking.
