| What is the most popular biometric technology | Fingerprinting |
| They are found on the soles of the feet and palms of the hands. When reading a fingerprint, in actuality, you are reading the ___________ _____________. | Friction Ridges |
| A close examination of friction ridges reveals that the surface is broken in an irregular fashion by these. | Sweat Pores |
| The identifiable aspects of a fingerprint (that which makes every print unique) are called what? ...aka? | Minutia aka Ridge Characteristics |
| True or False. As the fingers grow and age , the fingerprint will begin to change noticeably. | False. Fingers will grow and the print will enlarge, but the ridge characteristic remains unchanged. |
