Fingerprints’ primary function exceeds mere identification: fingerprints help us to grip things! These complex patterns of ridges and valleys provide the traction we need to pick up everything from a pencil to a slab of cement. Interestingly, the uniqueness of each individual’s fingerprint is more coincidental than genetic – they form mostly based on happenstance. Our movements in the womb are actually the primary factor determining the shape and structure of our fingerprints. This haphazard formation makes it so that no two fingerprints are alike.

Fingerprint Recognition

Biometric technology uses a scanner to detect and analyze your fingerprint. There are two kinds of scanners: optical and capacitance.

  • An optical scanner uses hundreds of light-detecting diodes to take a picture of your finger, using a technology not far distant from that which you find in your digital camera.
  • A capacitance scanner uses tiny, electrical sensors and your finger’s natural electrical charge to receive and store energy. The distance from these scanners affects the scanners’ ability to store a charge. So if your skin is farther away from the sensor, the sensor will store less charge. The ridges of your finger will be closer to the sensors than the valleys, and this contrast makes it possible for the sensor array to create an accurate picture of your fingerprint and compare it against the pattern of the lock’s administrator’s fingerprint.

It’s thanks to this technology that we’re able to more safely and conveniently store valuables and firearms. To make the most of your fingerprints, contact your biometric gun safe experts.
