Accepting Visa as a merchant
Visa is a four-party scheme: it sets the rules and operates the network, but it does not contract with you. Your acquirer does, and the price you pay is interchange plus scheme fees plus acquirer markup. Only the last of those is negotiable, which is why understanding the split matters more than the headline rate.
How your Visa rate is actually built
Interchange flows to the issuer and is capped in regulated markets. Scheme fees flow to Visa and are neither capped nor negotiable, and they have grown steadily as a share of total cost. Acquirer markup is what your provider keeps. Under pass-through pricing you see all three. Under a blended rate you see one number, and the blend is where a provider absorbs interchange reductions without passing them on.
Authentication is changing: DAF sunset and Payment Passkey
Visa has said it will sunset the Digital Authentication Framework 3D Secure programme in September 2026 as it transitions to newer methods including Visa Payment Passkey, intended to cut friction while maintaining strong authentication. For any merchant whose checkout depends on a specific 3DS configuration, that is a roadmap item with a date rather than a background detail, and it is a question worth putting to your PSP now rather than in September.
Recurring billing: the Original Transaction ID
Visa recommends consistent use of the Original Transaction ID to link an initial cardholder-initiated transaction to subsequent merchant-initiated transactions, across both token-based and PAN-based flows. The stated benefit is that issuers can identify individual subscriptions and validate consent, which improves authorisation outcomes and reduces unnecessary declines. If you run subscriptions and nobody has confirmed OTID is being populated correctly, that is a direct authorisation-rate lever sitting unused.
Monitoring and disputes: VAMP and CE3.0
The Visa Acquirer Monitoring Programme replaced the older fraud and dispute programmes with a single combined ratio, and the final stricter thresholds came into enforcement on 1 April 2026. Merchants need to stay below a 1.5 per cent VAMP ratio and a 20 per cent enumeration ratio, with a charge per violation in any month over threshold. Separately, Visa is expanding the scope of Compelling Evidence 3.0 from 24 October 2026. Both change the economics of disputes rather than the fee, and both are frequently invisible to the person who negotiates the contract.
Australia: what changes on 1 October 2026
The RBA Conclusions Paper of 31 March 2026 removes surcharging on eftpos, Mastercard and Visa from 1 October 2026, lowers domestic interchange caps, introduces caps on foreign card interchange and requires networks and large acquirers to publish their fees. From that date Australian merchants cannot recover acceptance cost from customers, and whether the interchange saving reaches them depends on pass-through versus blended pricing.
Which payment provider supports Visa?
Adyen, Checkout.com, Stripe, Worldline, Nexi, Cybersource and Global Payments all document Visa acceptance, among others, as does every acquirer in the market, which is exactly why support is the wrong question. Ask instead how your Visa volume is priced, whether interchange and scheme fees reach you as pass-through or blended into an average, and what your effective rate has done over the last twelve months.
Reviewing what card acceptance costs you
What you pay is set in your acquiring contract, not by the scheme. Start by establishing whether you are overpaying your PSP, or move straight to cutting your PSP costs, where interchange, scheme fees and markup are separated before anything is negotiated.
