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. | |||||||||
