Digital currency payment gateways enable travelers to complete online airline ticket checkouts. The checkout system’s architecture allows users of the mobile app to seamlessly move to their digital wallet to authorize flight payments before returning to the airline’s app to obtain e-tickets. Desktop users opting for this payment method select the digital option at checkout, scan a QR code displayed on-screen with their mobile device, and approve the transaction within their wallet. Once the payment is validated across the network, automated systems promptly generate flight itineraries and electronic travel documents.
