When you use pay as you go, you need to touch in at the start and touch out at the end of all Tube, DLR, London Overground, TfL Rail, Thames Clippers River Bus services and National Rail journeys. If you don't, we don't know where you've travelled, so we can't charge the right fare for your journey.
We call this an 'incomplete journey' and you could be charged a maximum fare. If you don't touch in at the start of a journey, you're also liable to pay a Penalty fare or you could be prosecuted.
A maximum fare is £8.00 in Zones 1-9 (or up to £19.80 for travel outside the London fare zones) and does not count towards a daily cap.
When you use pay as you go to travel on Thames Clippers River Bus services, only touch in at the start of your journey when instructed to do so by a member of staff and remember to touch out again at the end. If you don't, you could be charged a maximum fare of up to £7.50 for an incomplete journey.
You can get an incomplete journey if you don't touch in at the start, or touch out at the end, of your journey on Tube, DLR, London Overground, TfL Rail, National Rail services in London and on Thames Clippers River Bus services. You're more likely to do this if you're at an unfamiliar or busy station or pier, or if your journey's been disrupted. Other common reasons for not touching in and out are:
You should always touch in and out, even if the gates at stations are open. Where there are no gates you should use a freestanding yellow card reader. Freestanding yellow card readers are located at station entrances, exits and platforms.
If you need to change stations during your journey, for example, when changing from Clapham North to Clapham High Street station, you will need to touch out at Clapham North station to exit and touch in at Clapham High Street station to continue your journey. You may also need to do this at different gates within the same station like at Waterloo, Victoria and Kings Cross.
If you're changing trains on the Tube, London Overground, TfL Rail or National Rail and not travelling through Zone 1, you could get a cheaper fare by touching a pink card reader with your Oyster card. Find out more about pink card readers.
We recognise that there are times when you can't touch out as you leave a station, during a major sporting or entertainment event, for instance when we leave the gates open to help with congestion. On these occasions we'll attempt to complete your journey automatically.
We also know that people can sometimes forget to touch out. When this happens, we'll also attempt to complete your journey.
If you're due a refund when we automatically complete a journey, it will be loaded on to your Oyster card automatically when you next touch your card on a yellow card reader as part of your journey.
If you think that you might have an incomplete journey on your Oyster card, you can check your journey history in your contactless and Oyster account.
You can apply for a refund if you were charged a maximum fare because you didn't touch in or out for reasons beyond your control.
