Yes, as of 2026, all official London "Black Cabs" are legally required to accept cashless payments. This regulation was implemented by Transport for London (TfL) to ensure that passengers have a consistent and modern payment experience. Every licensed taxi must be equipped with a functional, card-industry-approved merchant terminal that accepts all major credit and debit cards, including Visa, Mastercard, and American Express. These terminals also support contactless payments via mobile devices, such as Apple Pay and Google Pay. The payment terminal is typically located in the passenger compartment, allowing for a secure and private transaction. While drivers are required to accept cards, they still accept cash if the passenger prefers it. If a driver’s card machine is broken, they are technically not supposed to be working or must inform the passenger before the journey begins. For travelers, this means you can land at Heathrow or walk out of a Soho restaurant without needing to find an ATM, as the iconic London cab has fully embraced the digital economy while maintaining its traditional charm.
