You can buy ABC on board from any bus driver when you start your journey. The ABC ticket product will be loaded onto your current smartcard, whether it’s an Xplore Dundee Discover card, a StagecoachSmart card or your National Entitlement card. If you don’t already have one, the driver will give you a new smartcard.
After the ABC ticket you’ve bought has been loaded onto your smartcard, just place the card onto the ticket machine as you board the next bus and tell the driver where you’re going.
