Mobile commerce, or m-commerce, is on the rise. Smartphones and tablets have always come in handy for on-the-go product research, but shoppers are increasingly depending on their mobile devices to facilitate every step of the buying process. Market research firm eMarketer expected U.S. retail m-commerce sales to jump almost 40 percent between 2015 and 2016 to $123.13 billion. The same source predicts that by 2020 mobile commerce will reach $242.08 billion in U.S. sales.
