Good point. How does the ‘inspector’ thing work with Oyster cards? Can they ping the card and see when it was last used, to verify where you got on the train and what time it was?
And how does it work with contactless payment cards?
I pay with my HSBC card and an inspector gets on…..do I just wave my HSBC card at him and say I’ve swiped it? What is to stop me from just walking through an open gate and then if an inspector challenges me, just say I paid with my bank card?
Yes, Oyster cards have a very limited amount of data on the card including when they were last touched in/out and balance, which is enough for an inspector to see if you’re being naughty or not.
TFL don’t get that sort of data from contactless so it’s all a bit awkward – inspectors can read a card and that data goes back to get reconciled at the end of the day (along with your journeys as they don’t know what to bill until the day is over). If you touched in, got checked, then touched out within a normal timeframe then all is well. If you hadn’t touched in then they take the penalty fare at the end of the day – if you do that twice then your card gets blocked.
It’s not really a problem as long as you know which card you’re using for travel and stick to it.
