What if stores had PhoneZones where customers could tap into all kinds of customer service options through their cellphones? Rohit Bhargava starts a discussion on his Influential Interactive Marketing blog, saying a photograph of a barcode could give  shoppers immediate access to all sorts of price and product information. I’d like to see it do even more, like fetch a salesperson, tell what’s in stock, download coupons, display video recommendations, or even GPS an item and hear “you’re getting warmer” to find anything fast. What frustrations might it solve for you?
