How long does a fingerprint last in a system if not used for 7 years
Fingerprints can last for years on surfaces depending on factors such as the surface material, level of cleanliness, and environmental conditions. Fingerprints can be preserved and lifted with proper techniques for analysis even after a considerable amount of time has passed since they were deposited.
Fingerprints can last on gold surfaces for varying amounts of time depending on factors such as how frequently the item is touched, the oils and residues left behind, and environmental conditions like humidity levels. In general, fingerprints can commonly persist on gold surfaces for days to weeks before naturally fading or being removed with cleaning.
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.
Well, there are 2 types that you can recycle. flat cardboard and corrugated cardboard.
