In the Western Union in the 30s of the 20th century worked 14 thousand couriers delivering telegrams. The size of the commission fee for the transfer is charged according to the Western Union tariffs and depends on the amount of money sent. In 1995, First Financial Management was acquired by First Data Corp. (the deal amounted to $ 7 billion), and Western Union Financial Services became a subsidiary of First Data. July 3, 1884 the company's shares were included in the calculation base for the newly created stock index Dow Jones Transportation Average. Payment systems are one of basic elements of infrastructure of e-commerce. In 1914 Western Union engineers invented the first payment card - a prototype of the modern credit card. In October 1871 the company Western Union began to provide money transfer services, drawing on its own extensive telegraph network.
