As of 2026, the vast majority of taxis in Spain—especially in major cities like Madrid, Barcelona, Seville, and Valencia—are legally required or highly expected to accept credit and debit cards. In cities like Madrid and Barcelona, local regulations mandate that every official taxi must be equipped with a working Point of Sale (POS) terminal for card payments (including contactless and mobile pay). While you might still encounter an occasional "broken" machine in rural areas or small towns, the standard for urban transit is digital-first. Travelers are always advised to confirm with the driver before starting the journey by asking, "¿Se puede pagar con tarjeta?" (Can I pay by card?). Additionally, many travelers now use apps like FreeNow or Cabify to book official taxis, which allows the payment to be handled automatically through the app, similar to Uber. Even though cards are widely accepted, keeping a few small Euro bills (5€ or 10€) is a good backup for very short trips or in case of technical connectivity issues in older historic districts.
