In 2026, the vast majority of taxis in major global cities now accept credit and debit cards, as well as mobile payments like Apple Pay and Google Pay. This shift has been driven by local government mandates and the intense competition from ride-sharing apps like Uber and Lyft. In cities like London, New York, and Tokyo, it is now an official requirement for licensed taxis to have functioning card terminals; in fact, a London cabbie can be fined if their machine is "broken" while they are in service. However, in smaller towns, developing regions, or "off-the-beaten-path" destinations, cash is still king. Even in 2026, many independent drivers prefer cash to avoid processing fees and may claim their terminal is down to encourage a cash tip. A "pro-tip" for international travelers is to always ask "Card okay?" before entering the vehicle. While we are approaching a "cashless" era in urban transit, carrying a small amount of local currency remains a vital backup for those rare moments when digital networks fail.
