Human fingerprint experts are able to examine a maximum of 60 fingerprints per hour. In contrast, computerized systems currently in operation can search at rates of 200 prints per second. The time required for the search is determined by the number of characteristics checked. Individual PRINTRAK systems cost about $1.5 million and make regional programs or lease/purchase arrangements necessary. However, storage limitations and system performance hamper trends toward centralization and regional programs, as illustrated by California's experience. In addition, many systems are limited in that computer processor examines only one print at a time. The parallel processing developed by NEC Information Systems increases the processing speed dramatically, however. Several firms are now developing parallel processors for commercial use. Thus, computer technology has progressed to the point where a national system can be envisioned that could process at least 36,000 prints per day. 18 notes.
