It's to validate that the fingerprints of the person arriving are the same as the fingerprints of the person who got the passport.
Which you don't need to do, because the fingerprints are in the passport (cryptographically secure so only an authorized reader can access them, and only when able to OCR the inside of the passport). They're signed by your issuing government, so they're much harder to forge than the physical document.
