Open any app or website where you want to pay, and at checkout, select “Credit or Debit Card.” Enter your Revolut virtual card details — found in the Revolut app under “Cards” → choose your virtual card → tap “Show Card Details.” Input the 16-digit card number, expiry date, and CVV. Complete the payment — your purchase will draw funds directly from your Revolut balance in real time. For added security, some payments may require 3D Secure authentication via app approval, SMS, or biometrics. You can also add your virtual card to Apple Pay, Google Pay, or Samsung Pay for one-tap checkout. No need to top up separately — as long as your Revolut balance covers the amount, your virtual card works instantly, anywhere Visa or Mastercard is accepted online.
