Card verification
Checks used to confirm a card is genuine and the user has legitimate access to it.
Card verification is the set of checks used during authorisation to confirm a card is genuine and the user has legitimate access to it. These include CVV/CVC validation, Address Verification System (AVS) checks, 3D Secure authentication, and increasingly biometric and device signals returned through the issuer’s authentication app. Each check returns a result that the merchant and acquirer use to decide whether to accept the transaction.
What it means for travel businesses.
Card verification matters most in travel where bookings are high value, card-not-present and committed against non-refundable supplier inventory. A weak verification stack means more chargebacks survive representment; a heavy-handed one breaks conversion on legitimate customers mid-booking.
A travel booking is not the place to find out that the verification stack is too aggressive. A customer mid-checkout who hits an unnecessary block is gone, and the operator never knows what the booking would have been worth. A customer who passes verification despite weak signals is the start of a chargeback months later.
The travel businesses with healthy verification stacks segment the response by booking value and customer signal. A £100 ancillary does not need the same depth of verification as a £6,000 itinerary, and treating them the same way costs revenue on the small end and bookings on the large end.
How felloh handles it.
felloh keeps verification signals attached to the booking so risk and finance teams can see why each payment was accepted or refused and respond with consistent evidence when a dispute appears.
The Transactions view records CVC, AVS and 3DS outcomes against every payment, with verification status surfacing alongside the booking trail. Risk Analysis aggregates the picture by booking value, issuer and channel so over-blocking and under-verifying patterns are both visible.
For fraud teams calibrating the verification stack, the feedback loop is finally closed. Adjustments to verification policy can be measured by booking outcome — captured, settled, disputed — rather than by anecdote.
