Passengers are being warned to use their Oyster Cards correctly or face paying more for their journeys.
From Sunday, if passengers do not touch the electronic smartcard on the reader on entry or exit to a station, they could be charged up to £4.
The cost of not doing so could rise to £5 if journeys are started or ended at certain national rail stations.
