Seal is the great way to check if a product is genuine or fake, especially luxury product or for artists, creators...

"We come from a family of creators. Our mother frequently saw her products get imitated, so we know firsthand how devastating the impact of counterfeiting is. Our family suffered from it." - Founders of Seal

But I like that this technology can be use also for medicine as @xabi says, it can save life.
