Why do I have a £0.10 charge from Transport for London (TfL)? When you use your Starling card on public transport (like TfL) - they'll do a card check, which will show a small payment of £0.10. They'll update the amount once they work out your fare after a few days.
If you still feel you've been incorrectly charged, you'll then need to contact TfL to resolve this for you. If you've been charged a maximum fare because you've touched in with one card and touched out with another, we're only able to refund the charge that applied to your Barclays debit card or Barclaycard.
Supports cash: If you want to pay for your transport in London using cash, you can buy and top up an Oyster card with cash. This is normally a lot more cost effective than paying for a cash ticket, with the rare exception of a one-off single journey as you have to consider the cost of the Oyster card.
Missed Tap Off CostIf you don't have a default set on your card and you forget to tap off at the end of your trip, you'll be charged the fare to the last stop on the train line or bus route and with your fare type and any applicable loyalty discounts applied.

It is significantly cheaper to travel in London using an Oyster card than it is to purchase individual tickets for each trip. The only reason you would want to just buy individual tickets is if you are only using public transportation once or twice during your stay.
