Frequently
asked questions

FAQ Image

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.
