As of 2026, paying for trains in Florence is largely a contactless and digital experience. For regional travel (like a trip to Pisa or Siena), the most common method is the "Tap-and-Go" system at the station or purchasing tickets through the Trenitalia or Italo apps. You must validate regional tickets before boarding by tapping your card or scanning a QR code at the green-and-white kiosks; failure to do so in 2026 can result in an immediate on-board fine of over €50. For high-speed trains (Frecciarossa), tickets are best bought online in advance to secure a seat and a lower price. At the main station, Firenze Santa Maria Novella, self-service machines accept all major international credit cards and digital wallets like Apple Pay. While traditional ticket windows still exist, they often have long queues, making digital purchases the preferred choice for modern travelers.
