Mobile commerce sales in the US are set to almost double this year, from USD10.5 billion in 2011 to top USD20.85 billion, according to a new report from Internet Retailer (IR). The research claims that the total will be driven by increasing consumer confidence in using their mobile devices for shopping, particularly purchasing holidays and breaks. eBay is set to account for USD10 billion of the year’s total, double its 2011 haul, illustrating the success of the firm’s mobile endeavours. The company recently revealed that it has surpassed 100m downloads of its mobile app, with a quarter of that total coming in the past six months alone.

IR’s report echoes a separate study from digital marketing group Econsultancy, which suggests that the number of consumers in the US and UK that claim that they have purchased products through their smartphone has doubled year on year. More than a quarter of US consumers have bought goods via their connected device, up from 12% last year, while the percentage in the UK has climbed to 25%, up from 13% in 2011.
