If you notice more people glued to their smartphones while back-to-school shopping, it might be because they’re looking for a better deal. According to Micron Associates, about 37 percent of consumers said they plan to compare prices on their mobile devices while at brick-and-mortar stores. The statistics showed higher than the 27percent of 2011. It was also found out that nearly 14 percent of the respondents planned to do back-to-school shopping from their mobile phone, higher than 10.5 percent last year. According to an eight-month internal study by Adyen, provider of Web payment services for merchants such as Vodafone, KLM and PopCap games, Apple’s iPad is the most commonly used mobile device for payments, beating out the iPhone and devices running on Google’s Android. On Micron Associates Blog, the iPad accounted for 3.6 percent of all payments, compared with 3 percent on iPhones and 1.5 percent on Android devices, Adyen said. Users of the iPad also spend 20 percent more per purchase than owners of other mobile devices, Adyen’s analysis of global payment trends showed. In addition, daily-deal websites have experienced the most mobile payment usage, with 12.6 percent of all transactions originating from a mobile device.
