I work for a retailer that has a card-to-check form of payment already, and I'm required to use that for my discount. I don't love the idea of having my checking account tied to a piece of plastic, but since it stays all in the family (card is only good at the retailer, and the only plastic card is in my wallet), I live with it.<p>That all said, there's no way I'd introduce a third party to this, well, party, and give direct debit access to my checking account to someone I don't know, who's security practices I don't know, and who's primary form of interaction is a freaking QR code - and I have nothing against QR, but I would never trust this to a single barcode of any kind. And the retailers are all going through all of this effort simply to avoid interchange fees and the impact ApplePay will have on them.<p>To me, the winner will be whoever balances security with ease of use, and ApplePay is the winner right now (and I say that having used Google Wallet). I use my existing cards and retailers I already go to, so it feels the same, but no actual, useful information is being transferred, so I'm better protected. All transactions show on my statement as if I'd swiped. If retailers shut me out in favor of proprietary systems that require work on my part, I will vote with my dollars and shop elsewhere.
