Virtual Visa or Mastercard?

All I hear about is people talking about virtual Visa cards.  This is funny because it shows the world that Visa is the strongest credit card brand on the plnet.  You will never hear “virtual mastercard” or American Express.  This is because Visa had the first movers advantage in the credit card business.  Just liek people say things like “give me a kleenax,” or “Just go and Google that,” Visa is a brand name that has become a noun in and of itself.  So, are there Virtual Mastercards like there are Virtual Visa’s?  Yes there actually are but do to the lack of popularity of Mastercard worldwide, it is not nearly as heard of by the general public.
