It costs 3 euro in cash to the driver to ride Tram 28 in Lisbon, or less if you pay with the rechargeable Viva Viagem pay as you go card. Or it can be free, with the purchase of the Lisboa card or the 24-hour Lisbon ticket.

Yes, as of 2026, you can pay for your fare on Lisbon's iconic Tram 28 using a contactless credit or debit card (including Apple Pay and Google Pay). This "Tap & Go" system was fully integrated across the entire Carris network to accommodate the massive influx of tourists and reduce the need for paper tickets. When boarding the vintage yellow tram, you simply tap your card or smartphone on the green validator near the driver. A single fare paid this way is usually slightly more expensive (around €3.10) than using a pre-loaded Navegante card, but it is much more convenient for occasional riders. However, because Tram 28 is extremely popular and often crowded, it is still recommended to use a 24-hour unlimited pass if you plan to hop on and off multiple times. Note that while you can pay by card, the vintage trams are small and do not have ticket machines on board, so "tapping" at the entrance is the only way to pay digitally without a pre-purchased ticket.
