Frequently asked questions

How does Sardine decide whether a prior verification can be reused?
Reuse depends on the user’s consent for the partner and on whether the user’s current tier meets the partner’s requirements. If it does, the partner receives a decision and a tier. If it does not, Sardine triggers a step-up for the missing checks only.
What data does a partner receive?
A status token or a data payload, depending on the scope the partner is approved for. Each retrieval records who received what, when, and under which consent.
How does consent work when a user reaches a new partner?
A verified user reaches a new partner through a consent step. Sardine records the user’s consent for each partner, and a partner can retrieve a verified identity only subject to that consent.
How does Sardine fit into existing KYC and AML tooling?
Sardine runs identity, fraud, and AML screening through one configurable rules engine and returns a decision, a tier, and policy metadata to your app. Verification and consent run embedded or by redirect.
Does my app handle user PII?
For consumer platforms and wallets, no. Sardine holds the verification and your app receives a decision, a tier, and policy metadata. Regulated service providers receive a status token or a data payload, depending on approved scope.
Can we set different requirements for each partner?
Yes. Set tiers, required attributes, and step-up triggers for each partner or program. Reports export by customer or by partner.
