Fingerprinting for kids and adults
Dactyloscopy is the term used by scientists to describe the practice of finger print identification. Fingerprints left by dirty or oily hands are visible to the naked eye, but investigators can also obtain latent fingerprints that are left behind when there is only sweat on the hand. They are not visible, but with dusting and other methods, they can be identified through a finger print matching system.
Past finger print identification techniques
When police purposely want to obtain fingerprints to keep on hand for future reference - such as when booking inmates or conducting fingerprinting for kids ids - they have traditionally used an ink blotter and sturdy, white paper to create visible fingerprints. Each finger on both hands is gently rolled in an ink pad and the ink on the hand is transferred to the paper with the same method. Nowadays, however, most law enforcement agencies use digital technology to scan prints into a computerized database. AFIS (automated fingerprint identification systems) is a popular national database used by law enforcement for fingerprint identification. AFIS or any other finger print matching system can match a new scan to prints in the database in a matter of minutes. The same process could take weeks or months to complete visually. Often, there were just too many files on record to ever find a match.
Finger print matching system
Fingerprinting for kids safety works the same way as it does for adults. An individual's fingerprints generally don't change. Even if a child burns his or her hand and blisters form, the new skin will grow back with the same pattern. However, it is still recommended that parents who use prints on children's ids periodically update these impressions, especially if they suspect there might be scar tissue on the hands.
Parents and caregivers using the Life-Prints program get regular reminders when it's time to update this and other data.
