The only place I regularly use it is at Whole Foods, where it actually works quite well and is a bit faster than a card. And given the glares one gets in the WF line, I would definitely be informed if it was inconveniencing anyone...

However, this looks to have been the result of concerted corporate effort and training (every clerk knows how it works, etc.). Can't see it catching on in a small business.

Agreed. My sister owns a coffee shop/chocolate shop. There's no advantage for her at all - its all for the customer. And most of her customers are making small purchases, trivial to do with cash or a card.
