The best thing about this service was its ability to be used with all major credit cards, so it could make sure that even if I had an American Express but not Mastercard or Visa they would still accept my account! There were some glitches in getting set up initially where there wasn't much support from their side as well - things like having multiple accounts open at once didn' t work very smoothly until we got past those initial hurdles.- But other than these minor issues everything worked great!! This allowed us access everywhere without needing any different forms/cards etc., just one form (and only because i needed more info).
