Direct Answer
The Fingerprint Scanner is an official third-floor inspection mechanic added in the August 27 Endless Mode update. Use it to verify visitor identity and detect subtle anomalies, but keep document, behavior, and current-shift rules in the same evidence chain instead of treating one scan as universal proof.
Current-build evidence
This inspection tools / medical / scanners record is maintained against the released build, not treated as a demo-only answer. The source ledger below was checked on September 26, 2026.
Where the official source identifies a mechanic but does not publish its hidden values, visitor answer, formula, or complete outcome table, this page preserves that boundary instead of filling it with an estimate.
