The traditional methods for obtaining fingerprints can destroy the fingerprint for further analysis and thus making the process not that helpful in the long run. There is a new technique that uses X-rays to detect salts from a person's sweat. If conditions are right, a fingerprint can be identified without altering the sample.

Traditional methods for obtaining fingerprints, which involve powders, liquids or vapors, can destroy the print for further analysis.

A new technique uses X-rays to detect salts from a person’s sweat. If there are enough of these salty residues, a fingerprint can be identified without altering the sample.

The alternative could prove advantageous in taking prints from certain difficult substances, like paper, wood, leather, plastic, and even human skin. It may also be useful in obtaining fingerprints from children, who have less oil on their skin.

Please visit the link provided for the complete story.

This new way of obtaining fingerprints is much better than the old way. Using the old way will not be helpful in the long run because it can destroy the print for later testing. This new way is great because it does not hard the original fingerprint. I cannot wait to see this in action on television!

Whats the benefit of preserving a fingerprint? Isnt the fact that its there and the identification of its owner the only priorities in fingerprinting? All of which is possible using current technology.

good question...

putting the fingerprint in a computer system is a great idea (which is already happining)...

but i guess the answer is to "share" the fingerprint with other agencies or something along these lines...

But wouldnt the fingerprint be preserved electronically when copies are taken from the crime scene are digitised? This technology prevents the damaging of the original fingerprint at the crime scene, which serves no purpose that I can see.

In fact that the technology can facilitate the lifting of prints from human skin and other difficult surfaces is sufficient reason enough to pursue it

I dont see how they can remove prints from human skin, wouldnt the same salts be present there too?
