- totalZero 7y agoI don't see how such a product should verify ownership, and I agree with the objection that a person can buy SmartWater and apply it to valuable items owned by other people. It is the high-tech equivalent of putting your thumb in the biggest piece of pizza when your brother opens the box, to claim it as your own.
