I encountered this article when it was referred to by F. William Engdahl in his today's article entitled "The Sinister Agenda Behind the Washington War On Cash", and you may want to also read that article. Colin Todhunter was the first (that I know of) to report this phenomenon, and now Häring uncovers more information on the hidden role of US-led Empire agents who have been promoting digital currency in India as the first experiment in what they plan to do in other countries including the US (as Engdahl explains).
It seems that the digital transformation of India's money supply is part of the Empire's plan to dominate the world, sometimes referred to by US imperialists (like George Bush, his father, Bill Clinton, etc.) as the New World Order. Control of money (along with many other weapons such as indirect and direct military incursions, "color revolutions", financial manipulation, sanctions, etc) has been a major economic weapon (mostly in the form of petrodollars) for their dreams of world domination. Häring explains how this digital money weapon would greatly facilitate the realization of the old fascist fantasy.
The business interests of the US-companies that dominate the gobal IT business and payment systems are an important reason for the zeal of the US-government in its push to reduce cash use worldwide, but it is not the only one and might not be the most important one. Another motive is surveillance power that goes with increased use of digital payment. US-intelligence organizations and IT-companies together can survey all international payments done through banks and can monitor most of the general stream of digital data. Financial data tends to be the most important and valuable.
Even more importantly, the status of the dollar as the worlds currency of reference and the dominance of US companies in international finance provide the US government with tremendous power over all participants in the formal non-cash financial system. It can make everybody conform to American law rather than to their local or international rules.
