What is a Stamp?
A stamp is a device used to imprint a mark, symbol, or signature onto a document or paper for the purpose of authentication or validation. It is usually made of rubber or metal, pressed onto special ink, and then applied to the desired surface. Stamps have been a key component of governance, authority, and trade across various civilizations.
