Lite info om Oyster
Oyster is London's ticketing and revenue system. At its heart is the Oyster card, a 'smartcard' which makes buying and using tickets easier.
An Oyster card can store up to £90 of cash which can be used to pay as you go, plus your Travelcard or Bus Pass.
It can be used on the Tube, trams, buses, DLR (Docklands Light Railway), London Overground and some National Rail services in London.
Pay as you go has several advantages over paper tickets:
Oyster single fares are generally cheaper
Credit can be used as you need it and doesn't expire
Daily price capping automatically calculates the cheapest fare for the journeys you make in a single day
Our aim is to ensure that Oyster always charges the lowest fare. Where it doesn't, we will refund the difference.
