Users of London Underground's Oyster card will no longer be charged more for certain journeys from the end of this month due to a new capping system.
The pre-pay Oyster card offers low prices on various transport services
From 27 February capping on pre-pay cards will be introduced allowing passengers to pay the lowest daily fare once every journey has been assessed.
The cap will apply at the appropriate one-day Travelcard or Bus Pass rate.
The London Transport Users' Committee (LTUC) has urged for capping to be introduced for a long time.
It has said that without capping the full benefits of the smart card could be not achieved.
Brian Cooke, LTUC chair, said: "We are delighted that capping is finally being introduced. This is great news for passengers, and London.
"Passengers will no longer be paying more than necessary for travel on the Tube, buses and other Transport for London services."
He said Oyster cards already offer the lowest prices on Tubes, buses, trams and the DLR and capping will further lower the daily spend for many passengers.
The LTUC represents the interests of transport users in and around the capital.
