|History||Taking Prints||Classifying Prints||Dusting|
Now that you know the history of fingerprinting, let's take our own. Then, examine and classify them.
Take a magnifying glass and study the patterns on your fingers.
1. What do you notice?
Fingerprints are impressions that are created
by ridges on the skin. When a person touches an object, the perspiration,
oils, and amino acids on the skin are transferred to the object, frequently,
leaving an impression of the ridge pattern. This is called a fingerprint.
No two people have the same fingerprints, not even identical twins.
The materials you will need to take your fingerprints are as follows:
1. Rub a small dark area with a pencil point on a sheet of white paper.
2. Press and rub your right index finger in the pencil-lead dust.
3. Place the sticky side of a piece of transparent tape on the dusted finger.
4. Take the tape with the fingerprint and tape it to a clean sheet of white paper.
5. Label the fingerprint to identify which finger you have printed.
6. Continue the process until
you have all ten fingers printed.
|Fingerprints may also be taken by pressing one finger at a time into an inkpad and then pressing and rolling each finger onto a sheet of white paper. Be sure to label each print. The prints may smudge if not done carefully. Also be sure clothing is protected.|
|Some employers require a background check using fingerprints. View an example of a background check form with Adobe Acrobat.|
