Yes, as of 2026, contactless payment has become the standard across nearly all major Italian urban transit networks. In cities like Rome (ATAC), Milan (ATM), and Florence, you can simply "tap" your physical credit/debit card or digital wallet (Apple Pay, Google Pay) on the green readers when boarding buses, trams, or entering metro gates. This "Pay-as-you-go" system automatically calculates the best fare for your journey, often capping at the price of a 24-hour pass if you travel extensively. Even regional operators, such as Busitalia in Veneto and various lines in Tuscany, have moved to 100% contactless systems. It is important to remember that you must always use the same card/device for every tap to ensure the daily fare cap is applied correctly. While you can still buy paper tickets at "Tabacchi" shops or kiosks, the convenience of contactless has significantly reduced the need for physical tickets. However, in very remote rural villages, you might still find older buses that require a pre-purchased paper ticket, so carrying a few Euros in change remains a wise "back-up" for off-the-beaten-path travel.
