Credit and debit (bank) cards – especially Visa and Mastercard – are widely accepted in London's restaurants, bars, cafes and shops. American Express and Diners Club cards are becoming more commonly accepted, although it is still advised to carry an alternative payment method with you.

Contactless cards are widely used in the UK and many businesses accept them as payment, up to a limit of £45 per transaction. Travellers can use a contactless card instead of an Oyster card when using public transport in London.

All contactless American Express cards, from any country, can be used for travel within London, however some non-UK Visa and Mastercards are not accepted, so you may need to check with your card issuer. Google Pay and Apple Pay on phones are also accepted.

Contactless payments may still incur an overseas transaction fee and these vary by card and by bank, so it is a good idea to check with your card issuer before tapping your contactless card.
