What is the difference between a name-based criminal history search and a fingerprint–based criminal history search?
A fingerprint-based search is the most accurate method available returning records based on matching fingerprints; a name-based search has a greater potential to match multiple candidates as the search relies on a comparison of similar sounding names or, if requested, names spelled exactly alike. With a name based search it is possible to match against records that do not relate to the person in whom you are interested, and it is possible to miss the record that does relate to the person in whom you are interested.
