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, London Overground and some National Rail services in London.

Oyster photocards enable students and under-18s to travel free or at reduced rates. Discounted travel is also available to London residents on Income Support and customers who hold a New Deal photocard.
