The Stasi’s technique of transferring top-secret messages worked like a piece of carbon paper. An agent would place a piece of paper impregnated with the chemical cerium oxalate between two pieces of plain paper. As the agent pressed down to write, the chemical was transferred to the piece of paper beneath.
