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 1991, Western Union has sold some low-profit division of the company AT & T, GM Hughes Electronics, and to some others. In the same year the company changed its name to New Valley Corp.
