In the Western Union in the 30s of the 20th century worked 14 thousand couriers delivering telegrams. In 1920, Western Union has implemented the world's first transmission of images over the ocean. Each money transfer is protected with control number, that allows you to track and to ensure prompt payment of money specified by you person. Separation of the companies had two objectives: first, to give Western Union the opportunity to develop more intensively, and secondly, to help First Data to return to its original activity (in 1992 the company separated from the payment system of American Express as an independent financial services company). One of the common kinds of money transfer is a transfer via the international system of Western Union. In 2007 the company made 167.7 million transactions on money transfers between individuals and 404.6 million transactions between physical and legal persons. In 1914 Western Union engineers invented the first payment card - a prototype of the modern credit card. Western Union provides consumers and businesses with fast, reliable and convenient ways to send and receive money around the world, to send payments and to purchase money orders. In 1884 Western Union has become a joint-stock company and was brought to the stock exchange. The company has entered in the first American stock index Dow Jones.
