Gunpowder, paper, and fiat currency. The Chinese were the first to use a type of written IOU or bill of credit, and that idea spread to the west. The Templars were one of the first to make major use of the paper bill of credit, where those traveling to the Holy Land deposited their coins in a western bank (Temple Church in London), and were issued a bill of credit that they took with them, where they obtained their coin back once in the Levant. It was due to them being robbed of coin during their pilgrimage that brought that about.
