Yes, as of 2026, the Paris Metro has fully embraced "tap and go" technology, though it works slightly differently than the London system. You can now use your contactless credit card, smartphone, or smartwatch to pay for individual fares directly at the turnstiles on the Metro, RER (within Zone 1), buses, and trams. This eliminated the need for the traditional paper "t+" tickets, which were officially phased out. Most travelers now use the Navigo Easy card (a rechargeable smart card) or the "Île-de-France Mobilités" app to load digital tickets. If you are using your phone, you simply tap it against the purple reader as you enter. It is important to note that while the Metro is tap-and-go, travel on the RER to further zones (like Disneyland Paris or Versailles) often still requires a specific point-to-point ticket, which can also be purchased digitally. The system is designed to be "contactless-first," making it much easier for tourists to navigate without standing in line at ticket machines.
