In 2026, paying for public transport in London is completely cashless and highly intuitive. The premier way to pay is using a contactless credit/debit card or a mobile wallet (Apple Pay, Google Pay, Samsung Pay) on your phone or smartwatch. You simply "tap" your card or device on the yellow reader at the start of your journey (and "tap out" at the end for Tube and Rail; buses are "tap in" only). The system automatically calculates the cheapest fare and applies daily and weekly "capping," ensuring you never pay more than the price of a Travelcard. Alternatively, you can use a physical Oyster card, which you can top up with "Pay As You Go" credit at station kiosks. For 2026 travelers, the contactless method is the high-value "pro-move" as it eliminates the need to buy or manage a separate transit card. This high-quality system covers the Tube, buses, trams, the DLR, London Overground, and the Elizabeth Line, providing a frictionless, integrated experience across the entire capital.
