NEW YORK: Increasing numbers of US consumers are using smartphones to research and buy products, a report has shown.

According to comScore, the research firm, 38% of smartphone owners - an audience currently standing at 90m people - have purchased goods and services through their handset on at least one occasion.

During September 2011, some 47% of individuals who acquired products via this route bought digital items like music, ebooks, ringtones, films and television programming content, the company found.

A further 37% bought clothing or accessories directly from a retailer, with tickets to events including movies, plays and sporting fixtures following on 35%.

In a demonstration of the integration between emerging digital platforms, 34% of the mcommerce population completed transactions on daily deals websites such as Groupon and LivingSocial.

This matched the total generated by gift certificates, while 32% of the mobile customer base opted for electronics like TV sets and computers.

Ordering food for delivery or pick-up, for example a takeaway pizza, scored 31%, hotel reservations yielded 29%, physical books registered 26%, and car rentals logged 24%, as did airline tickets.

Elsewhere, 13% of shoppers buying from a phone made purchases linked to the automotive category, suggesting this channel holds opportunities for a wide range of sectors.

"In September we saw two-thirds of all smartphone owners perform shopping activities on their phones, including comparing products and prices, searching for coupons, taking product pictures or locating a retail store," Mark Donovan, comScore's senior vice president, mobile, added.

Looking at the location of consumers as they bought offerings through their smartphone, 56% did so at home, and 42% engaged in this pastime at work.

Another 37% did so when travelling, and 36% actually utilised mcommerce tools in bricks and mortar stores.

Other outdoor sites, such as parks, schools and restaurants, posted a combined 42%, comScore's analysis revealed.
