Yes, you can pay on the tram in Portugal in 2026, but the method varies by city and cost. In Lisbon, you can buy a single ticket directly from the driver or an onboard machine for around €3.10 to €3.30, but this is the most expensive way to travel. Most modern trams now also accept contactless "Tap to Pay" with your credit or debit card at the validator. However, for the best value, locals and savvy tourists use the Navegante card (formerly Viva Viagem), which can be loaded with "Zapping" credit to bring the price down to around €1.50 per ride. In Porto, the historic trams (Elétricos) have their own pricing structure, and you can buy tickets from the conductor onboard. While cash is still accepted in many cases, the system is moving rapidly toward a "cashless" model; in 2026, having a contactless card or a pre-loaded transit pass is the standard for a hassle-free journey through the narrow, hilly streets of Alfama or the Ribeira.
