What it means
3DS2 is the newer version of 3D Secure, the authentication layer used by card issuers to verify online card payments before they are approved.
Why it matters in travel
Travel bookings are often high value and made across phone, email and web channels, so authentication can reduce fraud risk without moving sensitive card data through the sales team.
How felloh helps
felloh keeps authentication, payment status and booking evidence connected so finance and operations can see whether a payment has been authorised, paid and attached to the right booking.
