The highest published uptime here, no interchange markup, and no confirmation that it takes gambling merchants at all.
99.999% uptime across 365 days is the strongest reliability figure in this catalogue, and Finix puts a second unusual one next to it: no markup on interchange. Pricing comes as flat rate, dynamic or custom, with a subscription and per-transaction fee rather than a spread hidden inside the rate.
The platform is built for businesses that want to own their payments rather than rent them — one integration, a REST API with hundreds of configuration options, and underwriting, reconciliation and dispute management built into the same tooling. Payouts are a separate priced product.
Then the caveat that decides everything. Finix writes about iGaming and high-risk card processing, runs no gaming product line, and works inside the United States. Writing about a vertical is not the same as underwriting it, and that distinction is the first thing to settle.
Tech scores 9.8 — published uptime, one API, embedded operations tooling. iGaming fit falls to 4.2 because Finix stops short of saying it takes gambling merchants at all. Compliance is 2.0 with no licence, registration or certification published anywhere.
Five weighted criteria, 1–10. A criterion whose key field the provider does not publish is capped at 6.9 rather than scored on a guess. How we score →
Nothing is published on the site and nothing could be read from it. Ask for the authorised entity and check it in the regulator’s own register before you sign.
United States.
Cards.
Worth one phone call, and the call has one question: do you underwrite licensed gambling operators in the United States, yes or no. If yes, the technology is among the strongest here. If the answer is hedged, stop there and spend the time elsewhere.
Unconfirmed. Finix writes about iGaming and high-risk card processing, but runs no gaming product line, makes no underwriting statement and names no gambling client.
The company publishes 99.999% uptime across 365 days a year, the highest figure in this catalogue.
Flat rate, dynamic or custom, as a subscription plus per-transaction fee, with no markup on interchange — so the scheme cost stays visible and separate from the provider's margin.
