The number of mobile shoppers is expected to double over the next two years, from 393 million this year to 580 million by the end of 2014, according to JuniperResearch.
The report says the growth is the direct result of greater consumer confidence in the mobile device as both a content browsing and payment mechanism.
It also reflects the increasing importance of mobile as an e-retail channel, with retailers witnessing a marked uplift in mobile as a proportion of online transactions.
Mobile Payments for Digital & Physical Goods: Opportunity Analysis 2012-2017 found that both the average size and scale of purchases would continue to rise markedly, bolstered by larger volumes of regular, higher-value transactions such as the weekly shop.
But it’s not just mobile that is important as an e-retail channel – it is also migrating totablets, with average tablet transaction sizes already exceeding those on desktops and laptops.
However, the report cautioned that growth continued to be constrained by the fact that a majority of retailer sites are still not optimised for mobile browsing, registration or purchasing.
And concerns about transaction security were still paramount amongst end users, although the scale of these concerns was not yet being translated into consumer adoption of security solutions on the handset.
Report author Dr Windsor Holden said: “Consumers increasingly expect to be able to buy their products and services via their smartphones and tablets. Companies which do not offer this option face falling behind their competitors.”
