Why is that? The simple answer is advanced technology. Instead of rolling fingers and palms in ink, they are able roll them on a glass plate and a digital image is taken. Once the digial image of the print is checked for quality control by a technician, it is entered into the AFIS.
The Automated Fingerprint Identification Systems, or AFIS, is a national database that holds images of fingerprints that have been scanned in by computer. A technician can search the AFIS to determine if the person has been arrested previously, has a warrant out for their arrest, or has provided false identifying information. It usually take a few minutes for the AFIS to search over 5 Million fingerprint cards. It then generates three closest matches to the fingerprints searched. From there, the technician must compare the prints to make sure that are from the same person.
A latent print is print that is lifted off a surface (For example, a print that was taken off a window of evidence at at crime scene). These prints can also be scanned in to see if they can be connected to a person in the AFIS.
In CSI TV shows you see the person scan a print into the computer and a moment later a picture of the suspect pops up with all their information. Well in real life, when a techinician scans a prints into AFIS, it can take awhile. The technician must compare the unknown latent print with known prints of an individual and get a what is called an “AFIS hit.”
