Fingerrints have been found for thousands of years. They have been found on ancient Babylonian clay tablets, seals, and pottery. Bricks and tiles from Babylon and Rome have aslo been discovered holding fingerprints.
Most of these were deposited unintentionally in the process of making the craft. But some were also made to add decoration. Babylon had a smart idea to use fingerprints to put beside signatures to verify the identity and prevent forgery. After Babylon did this, it was like a virus, a few other countries followed their lead and started using fingerprints to verify the authenticity of documents.
