In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. America was on the verge of civil war and needed a reliable connection between the North and South. On the telegraph market of the USA at this time were operated with six large companies: American Telegraph Company, New York Albany and Buffalo Electro-Magnetic Telegraph Company, Atlantic and Ohio Telegraph, Illinois & Mississippi Telegraph Company, New Orleans & Ohio Telegraph Company, and the brainchild of Sibley & Co. - The Western Union Telegraph. Payment systems are one of basic elements of infrastructure of e-commerce. All you need for sending money via Western Union is to go to the nearest branch of Western Union, fill out the transfer printed form, show your passport and then send money.
