How long does a fingerprint last in a system if not used for 7 years
is possible to change fingerprints by chemicals for long time or short time?
Since fingerprints don't change, they should be good indefinitely.
1 to 2 months. My friend in California got it in 1 and half month last year (2011).

Do you really need cardboard? What can you use Instead of cardboard? Does it decompse? If so how long does it take to decompse?
Cardboard takes about 2 weeks to decompose in the ocean.
It has been used as a method to develop latent fingerprints on items of evidence. The fingerprints must be photographed as their visibility does not last. Iodine has been used when the evidence must not appear to have been examined, such as mail fraud cases where the fingerprints are developed and then the mail continues on it's way to allow authorities to trap the accomplice.
Well, there are 2 types that you can recycle. flat cardboard and corrugated cardboard.
You take a shirt and you rub around on the top of the photo if you do not the acid on your fingerprints will go through the picture when it is older. Isn't it weird?Thx,WildComet on Horse Isle 1
