The reminder comes just a week ahead of the introduction of contactless fares on the capital’s rail services next week, Tuesday 16th September.
Once the system is live passengers will be able to use a contactless debit or credit card to travel at the cheaper Oyster rate without having to top-up or maintain a separate card.
In addition to Oyster rate fares users will also benefit from daily and weekly fares caps which will ensure regular travellers always pay the lowest available fare for their journeys.
To ensure they benefit from the best fares, Transport for London is reminding passengers that they should always use the same card to travel and should ensure only that card is touched on the reader.
Passengers can avoid ‘card clash’ by storing their preferred payment card in a separate section of their wallet or purse from any other Oyster or contactless cards.
Last month it emerged that, during a trial of the new system, passengers tapped more than 2,000 incorrect cards on readers by passengers each day.
While none of the passengers were charged as a result of their error, once the system goes live those passengers could lose their entitlement to fares capping or be charged a maximum fare for having an incomplete journey registered on their Oyster card.
Shashi Verma, TfL’s Director of Customer Experience, said: “With the launch of contactless now a week away, customers can look forward to having an easier and more convenient way to pay for their travel, freeing them of the need to top up Oyster credit and helping them to get on board without delay.
“I would like to remind all of our customers to only touch one card on the reader to avoid paying with a card they did not intend to pay with.”
