What are the different fingerprinting techniques used in forensics?

There are several fingerprinting techniques, including inked prints, digital scanning, and chemical methods like ninhydrin.

Can you explain how the ninhydrin method works?

Sure! The ninhydrin method reacts with amino acids in sweat, producing a purple-blue color that reveals latent fingerprints.

What are the advantages of using digital scanning over traditional methods?

Digital scanning offers higher accuracy, easier storage, and the ability to enhance and analyze prints using software.

Are there any limitations to these fingerprinting techniques?

Yes, limitations include environmental factors affecting prints, the need for proper training, and potential for contamination.
