Thank you for the clarification. Although technology has progressed quite a bit, it is clear there is still more that needs to be developed. your point about sticking a phone out of the window at a drive through is clearly an important point. Another issue that has been taken up here is that of needing multiple apps -- one for each establishment.
I do not know what the answer is, but we are going to need some integration and consolidation down the road. NFS, Passbook, bitcoin, etc -- we need a universal, secure, and convenient way to pay. I would love for it to live in my phone so I don't need to carry a wallet full of plastic cards. We will also need some universal way to place orders so that I do not have to clutter my phone with apps for every food establishment that I visit. Until then, either folks like Wendy's create apps or sit on the sideline and wait.
Having said that, I congratulate Wendy's for taking a bold step and pushing us forward.
