Another invention of Western Union - time synchronization. In 1866, Sibley ordered the engineers to develop a Western Union telegraph system of stock quotes in real time. 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 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.
