I've actually been waiting for that question, so thank you for asking it.
My belief is that from a mobile perspective, we are just carrying the card. We're creating a different vessel into which you will place a MasterCard, Visa, American Express, or Interac card, but we're open to any type of card. It doesn't have to be a payment card any more. But there are merchants out there who love their store cards. They want to see gift cards that they've sold. They want to be able to distribute gift cards. You can do that all virtually, and therefore you can accept them very easily.
So although we had to build this whole system around the rigour of globally accepted payment networks—Visa, MasterCard, American Express, etc.—once it's in place with all those security layers, you can put other things on it that I think consumers will want to carry, because it's going to be so easy. They will be able to have mobile wallets that reflect their personality and where they shop.
I shop at Home Depot. I should carry a Home Depot card. I don't, because I just refuse to make my wallet any bigger. But if I had 50 store cards, or a whole series of gift cards in my mobile phone, it doesn't get any bigger; it's just memory. That's great for the consumer, but when the merchants see those cards, they're going to want to accept them.
Initially there will probably be no change, but as the ability to carry, the willingness to carry, and the ability to accept expand, as merchants and consumers embrace this new technology, I think overall fees will lower. All these alternative payment types in the mobile phone will be accepted by the merchants.
