Almost a third of US use smartphones for shopping activity

In-store price comparisons and browsing are the most popular options.

Although m-commerce is still a growing platform, researcher Nielsen says 29 per cent of American smartphone owners complete shopping-related activities on their device.

Shopping for a bargain is a high priority with 38 per cent performing in-store comparisons, while another 38 per cent choose to browse for items via mobile web or apps and one-third read online product reviews.

Nielsen, says: "Apps, which account for the majority of mobile phone time in the US, may be the key to shifting consumers from browsing products on their phone to making purchases on the spot."

The least popular activity is actual payments via mobile, with just nine per cent seeing their session through to the end. This is likely down to security, which we've reported in the past is a big issue for mobile users, believing personal details are likely to come under fire.
