Fingerprints do not match record?

I'm playing Papers Please. I see a citizen whose height doesn't match, so I fingerprint him. The name on the fingerprint slip ends up matching the name on the ID card, so I let him through. However, I get a citation anyway - invalid height, and fingerprints records do not match. Is this a bug or am I missing something obvious?

UPDATE: Ok, it seems that if I have a document from the person with a fingerprint on it, then I can match that with the fingerprint I just got, and this is consistent. If the fingerprints match, I approve, if not, I reject, and it's ok. However, if the person didn't give me their fingerprints, then it seems like a crapshoot. Even if the names match, sometimes I reject and it's ok, other times I reject and it says I should've let them in.

Solution 1:

From my experience, when there's an option for a fingerprint check you give one sheet to the person and another one is printed for you.

• If height/weight didn't match, it's enough for prints to match and name on the printed sheet should match the one in the papers.

• If names don't match, then prints must match and there should be a second name in the "alias" section of the printed paper.

By the way, appearance of the printed paper with correct name does not mean that fingerprints match. You need to get the sheet from the person and visually compare it to the printed one.
