The number of consumers that receive coupons via mobile devices will jump by 30 per cent next year to more than 500 million, according to a new report from Juniper Research. The growth will be fuelled by the integration of couponing platforms into the leading social networks, with Apple's Passbook also being seen as a catalyst for coupon deployment and adoption. However, the report warns that retailer reluctance to upgrade POS terminals to support mobile coupons is creating a bottleneck, and effectively delaying the deployment of mobile coupons. "POS terminals can have a lifespan of a decade or more, so understandably retailers are wary about disrupting the terminal lifecycle and investing in new technology," said Juniper Research's Windsor Holden.
