The device used for scanning live fingerprints into AFIS is called
Live scan. The process of obtaining the prints by way of LiveScan employs rolling prints or placing flat impressions onto a glass platen above a camera unit. The process of obtaining prints by placing a
ten-print card (prints taken using ink) onto a flatbed or high-speed scanner is called CardScan (or occasionally DeadScan). In addition to these devices, there are other devices to capture prints from crime scenes, as well as devices (both wired and wireless) to capture one or two live finger impressions. The most common method of acquiring fingerprint images remains the inexpensive ink pad and paper form. Scanning forms ("fingerprint cards") with a forensic AFIS complies with standards established by the FBI and
National Institute of Standards and Technology (NIST). To match a print, a fingerprint technician scans in the print in question, and computer algorithms are utilized to mark all
minutia points, cores, and deltas detected on the print. In some systems, the technician is allowed to perform a review of the points that the software has detected, and submits the feature set to a one-to-many (1:N) search. The better commercial systems provide fully automated processing and searching ("lights-out") of print features. The fingerprint image processor will generally assign a "quality measure" that indicates if the print is acceptable for searching. ==Speed==
