Best practices for rolled fingerprint capture using a livescan device
When a person’s fingerprints are enrolled into an AFIS (Automated Fingerprint Identification System), it is important that the images are cleanly captured with good contrast between the ridges and the furrows.
This is especially important when collecting fingerprints that may be used forensically so that criminals are properly identified. But on a more practical level, it costs time and money when the receiving AFIS (such as the FBI) won’t accept the fingerprints due to low quality.
Obtaining clear, legible fingerprints requires a combination of a high quality fingerprint scanner and a good set of techniques on the correct way to capture both flats and rolls.
