​
What Depends on What

The two strictness selects do nothing on their own. Document liveness check is the master toggle for both — with it off, a printed copy or a document held up on a monitor passes through unexamined no matter what the strictness is set to. Between the two face checks, Active 3D face liveness check takes precedence: enabling it replaces the static face capture step entirely and supersedes the passive Face liveness check. Turn on one or the other, not both, unless you specifically want the 3D flow.

​
Choosing a Strictness Level

Both selects offer Soft, Regular and Hard, and the choice is a fraud-versus-friction trade rather than a quality setting.
A denial from either check is automatic and happens before manual review. If you raise strictness, watch your denial rate before and after — the users you lose are disproportionately the ones on older phones.

​
NFC Reading

Reading the document’s chip extracts issuer-signed data directly, which is the strongest document authentication available — nothing about it can be forged by re-photographing a document. The two NFC settings differ only in what happens when the scan fails:
  • Optional NFC reading — users who cannot complete the scan carry on through standard verification.
  • Required NFC reading — a failed scan denies the verification.
Required NFC only applies to documents that actually support a chip, so enabling it does not block users whose document has none. See Liveness Checks for how these results are reported, and Verification Statuses for the values you’ll see on the result.
