Alphabet (NASDAQ: GOOG) is adding some new levels of versatility to Google Pay.

The payment wars will only end when central banks like the U.S. Federal Reserve, the People’s Bank of China (PBOC; the Bank of Canada, the Reserve Bank of India, the European Central Bank, and the Bank of England step in and take control of the payment system. That will be a repeat of what happened with paper money, which was originally printed by private banks but eventually taken over by Central Banks.

My prediction is lesser solutions like Microsoft Pay and Stripe will eventually be rolled into a larger payment solution. Eventually, there may just be one payment app; which will probably be managed by the Federal Reserve, or an international agency of some sort.
