Maybe I am not in the right demographic category to appreciate this. I like using cash for small purchases. I like the anonymity, the convenience and easy availability ( I typically carry some in my wallet). Most of all , I would not feel comfortable handing out my card to small shops or vendors that I hardly ever visit. For large purchases, like the couch example, most such stores already have cash registers that support Credit cards. I don't see them as using this service. Please note that I am not saying this is a bad idea. I am saying that it is positioned as an alternative to small cash transactions for small businesses. That would be hard to beat.
