Payment Authorisation Architecture
Human Verification
Authentication flow animates when you press Generate simulated verification proof · closes when you run a scenario or collapse Human verification
AffixIO returns proof, not approval • Issuer decision happens after proof evaluation •
Callable by PSP, issuer, or orchestration layer • Verification without exposing raw personal data
How AffixIO Fits into Authorisation
AffixIO is a callable pre-decision proof layer
AffixIO sits before the issuer sees the transaction. The PSP or orchestration layer calls it to check whatever conditions matter: spend limits, merchant rules, account standing, device trust, whether the terminal is offline, or if a machine is acting on someone's behalf. It hands back a proof, nothing more. The issuer takes that proof, runs it through its own logic, and makes the call. The auth response only comes back once the issuer has decided.
