Juniper Research releases results of study on retail mCommerce. Retail mobile marketing spend is predicted to hit $55 billion annually by 2015. Retailers are set to spend $28 billion on mobile marketing campaigns in 2013. Augmented reality, NFC, and coupons are highlighted as innovative platforms for retailers to integrate mobile in-store. Despite the figures and opportunities, however, Juniper warns that many companies still don’t offer mobile websites, registration, or payments.
