By the beginning of the twenty-first century, computers were able to scan fingerprints and palm prints, and store images of those prints in automated identification databases. Fingerprints develop during early fetal life. Mapping the volar pad precedes ridge formation. Identification will always require a trained and skilled human being to make the physical comparison. Once an impression is rendered visible, documented, and recorded; it must be compared with a known-recorded print of an individual in order to identify it. Fingerprint pattern types are predominantly affected by the symmetry of the volar pad. Additional research brought the development of fluorescing chemicals that could be applied after cyanoacrylate ester.
