Consumer use of smartphones and tablets is helping to drive the growth of mobile transactions in retail. Chain Store Age spoke about the growing trend with Don Kingsborough, VP retail services, PayPal, which recorded $14 billion in mobile payments in 2012 and expects to exceed $20 billion this year. According to Kingsborough, PayPal is well-positioned to tap into mobile payment growth as it already has three key elements in place: a large consumer base (55 million-plus in the United States), a network of merchant partners and "ecosystem" partners.
