SmartWater uses forensic technology to form a security mark on items which are all but invisible to the naked eye.

Each batch is unique, like a fingerprint, meaning stolen goods can quickly be identified and returned to their rightful owner.

It also transfers onto hands and clothes, meaning anyone who has handled the goods will also be marked.
