The New York Times documents a recent study conducted by Nielsen Mobile among 30, 000 wireless customers, that estimates over 3.6% of all mobile phone users in the United States have used their phones to pay for goods and services. This figure is expected to grow in the future, with nearly half of all users of text messages and mobile internet, stating that they hope to make a mobile phone purchase in the future. However, security concerns remain. 41 percent of the consumers who transmit data said security was the reason they didn’t buy things via their mobile phone.
