text: I think Mastercard would do better in the long run, vonage has a good perspective for the future because comunications are fastly going to ip but high competition and their model is not unique.  Burger King is good right now but the future of fast food depends on healthy menus and I do not know how they will adapt.\n\nMastercard is in the electronic payment system which is still growing and debit cards, store value cards and smart cards are just getting started so they have the best future of the three.
