Make sure you pay the right fare by touching in and out on the yellow card readers at the start and end of your journey on Tube, DLR, London Overground, TfL Rail and National Rail services.
You only need to touch in on bus and trams.
Find out more about touching in and out.
On Thames Clippers River Bus services, only touch in on the yellow card reader when asked to do so by a member of staff and remember to touch out again at the end of your journey.
If you're changing trains to avoid travelling through Zone 1 and you see a pink card reader, touch your card on it to pay the right fare.
If you don't touch in or touch out with your Oyster card, we can't tell where you've travelled, and can't charge you the right fare. This is an 'incomplete journey', and you could be charged a maximum fare.

You can't use cash to pay for your bus fare. If you don't have enough credit on your Oyster card to pay the £1.50 fare or your Bus & Tram Pass or Travelcard has just expired, you can make one more journey on a bus. You must then top up your pay as you go credit to clear the negative balance before you can use your Oyster card again or before you can renew a Travelcard or Bus & Tram Pass. Find out about cash free buses.
Every journey has its own maximum journey time. If you travel longer than the maximum journey time when you pay as you go, you could be a charged a maximum fare.
Only one Oyster card can be used per person per journey. That means if you are travelling in a group, each person will have to use a separate Oyster card, or find another way to pay for their journey.
