Fingerprints form an essential category of physical evidence which is individualized. Over time the field of fingerprint science has experienced new developments. The methods used to establish latent prints, imaging, and AFIS technologies have been improved tremendously. The automated fingerprint identification system can carry out live scans and automatic computer searches. Latent fingerprint processing has been developed to include physical, instrumental, chemical, and combination techniques. Fingerprint technology employs advanced fingerprint identification such as micro-X-ray fluorescence and forensic science advances. The development of the Interstate Photo System has enabled easy latent fingerprint identification.
Fingerprint technology is the primary key to the success of police investigations and crime detection. By identifying fingerprints collected from the crime scene, the police can identify all persons present when it happened. As a result, the technology has improved investigations and aided in sentencing, parole, and probation rulings. In addition, advancements in fingerprint technology have enabled law enforcement agencies to keep track of the criminal records of suspects, their previous arrests, and convictions.
