Fingerprint is an identity that exists in every human being that distinguishes humans from one another, because every human’s fingerprints patterns is unique. But have you ever experienced a problem with your fingerprints? For example your fingerprint is difficult to scan or its missing? Could this happen?

Before discussing the disappearance of fingerprints, let’s first discuss what fingerprints are.

Fingerprints have a very influential function for humans. However, the main function of the fingerprint is to increase the friction force when holding an object object and the effective identification of an individual.

With fingerprints, a person can hold objects more tightly. That is why someone who loses his fingerprint is vulnerable when holding a slippery object such as a glass. Glass can fall if no other hand supports it.

Fingerprints can be used to find out someone’s identity. That’s because everyone has a unique fingerprint, not exactly the same as other people. Even between one finger and another finger has a different fingerprint pattern even in the same hand.

Who is studying fingerprints?

Fingerprint is a “pure” science of police. Polices studying fingerprints for identification or investigation in completing a crime case. Fingerprints are actually thickened and thinned skin forming a “ridge” on the palm of the finger that forms a pattern, fingerprints will not disappear until a person dies and rotten, scratches or cuts usually when the skin changes will form the same pattern. Unless the skin has severe burns.

Fingerprints can be used for disclosure of crime, for example from latent fingerprints (fingerprinting using chemical powders) obtained from goods at a crime scene, or items used to “commit crimes” such as pistols, knives, screwdrivers, etc.

Causes of fingerprint disappearance

In this world, there are people who suffer from abnormalities of adermatoglyphia where the person with this disorder does not have fingerprints.

Then how difficult is life without fingerprints? Someone who does not have fingerprints will encounter difficulties in managing citizen ID card, passport, driver licenses, including accessing doors and gadgets that use fingerprints as a security system.

Fingerprints are actually hard to disappears, except that the skin on the fingers of a human is completely gone.

In general, there are two causes of fingerprints disappearance – genetic and nongenetic.

If the cause is not a genetic disorder, fingerprints tend to be able to re-appear. For example, cases experienced by idiosyncracy (people whom suddenly lost their fingerprints) due to exposed or direct contact to abrasive liquid or materials. The disappeared fingerprint should be returned, because regeneration occurs.

Then, what about the disappearance of fingerprints due to genetic disorders?

For this one it seems permanent. Abnormalities of fingerprint loss since birth are called dermatopathia pigmentosa reticularis (DPR) and Naegeli syndrome. Based on the results of the research, the cause is the absence of keratin 14 which forms the fingerprint. This disorder is only passed on to girls.

Another impact caused by the absence of keratin 14 is that people with this disorder have very brittle hair, ridged nails, and thickening of the palms and soles of the feet. It can even cause non-functioning sweat glands.

As a result, patients are susceptible to heat stroke. Even mild activity can cause additional heat that can threaten patient safety.

In addition to the two causes above, it turns out that chemotherapy can also causing disappearance of someone’s fingerprints. Like what happened to Singaporeans who lost their fingerprints after receiving capecitabine treatment for three years.

The symptoms experienced are the skin of the palms and feet swelling, peeling, and painful. Until finally the fingerprint pattern is lost. Similarly, what happened in New York, which happened to 65 years women. The woman who underwent breast cancer treatment was denied by bank service because she did not have fingerprints.

Do you know that it turns out that adults who have dry palm skin will be four times more difficult to verify their fingerprints through a computerized scanner than those who don’t?

Not only dry, hands that have had dermatitis or eczema are also difficult to detect for scans. A new study in Malaysia has shown that cracked or swollen skin can damage the pattern of fissures or uniqueness found in individual fingerprints. This pattern of gap or uniqueness of fingerprints can also be damaged due to skin inflammation caused by allergic reactions
