Each money transfer is protected with control number, that allows you to track and to ensure prompt payment of money specified by you person. Most service points of Western Union work in the time convenient for customers throughout the week and throughout the year. In 1866, Sibley ordered the engineers to develop a Western Union telegraph system of stock quotes in real time. In the early 60s Western Union has put into operation transcontinental microwave system of data transmission via radio waves, completely replacing the web of telegraph poles and wires. 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.
