More stores are processing instant payments using mobile devices, enabling customers to bypass the checkout counter.
The women's shoe department at Nordstrom's flagship store in Seattle is bustling. Shoppers are trying on everything from stilettos to rain boots — and when they're ready to buy, they can pay up right where they are.
