In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. Each money transfer is protected with control number, that allows you to track and to ensure prompt payment of money specified by you person. In 1864, fearing the laying of long underwater lines, Western Union offered to carry out laying of telegraph lines to Europe through the Russian Alaska under the narrow Bering Strait and then to Siberia with branching in the major cities of Europe. Payment systems are one of basic elements of infrastructure of e-commerce. In 2007 the company made 167.7 million transactions on money transfers between individuals and 404.6 million transactions between physical and legal persons. Number of active holders of "Golden Card" of Western Union amounted to 9.5 million people worldwide.
