Mobile devices like smartphones and tablets now account for over half of all time spent online. Smartphones are integral to the shopping process, with many consumers using their phones to research products in stores. Tablets are more for leisurely browsing and online shopping at home. To better reach consumers across channels, retailers need to provide omnichannel experiences that unite online and in-store shopping. Mobile technologies like coupons, loyalty programs, checkout, and wallet features are increasingly driving the growth of mobile commerce.
