A recent Nielsen survey of U.S. smartphone owners who report using their mobile phones while shopping in a store, indicates that consumers use their phones differently depending on the type of store. For example, mobile couponing (either using or requesting a coupon) is most popular at grocery stores (41 percent of mobile shoppers reported using coupons there), department stores (41%), and clothing stores (39%). The more considered the purchase, the more smartphone shoppers rely on their smartphones: At electronics stores, the vast majority of smartphone shoppers read reviews (73%), compare prices with other retail outlets (71%) and scan QR codes to get more product details (57%).
