Top e-retailers apply artificial intelligence, bots and a mobile-first approach to push mobile commerce well beyond sites and apps. Many retailers are likely familiar with, and perhaps even own, a Staples Easy Button. They may have even tapped the tchotchke a time or two, prompting the bright red plastic button to cheerfully chirp the office supply retailer's tagline, "That was easy!" But calling out the retailer's slogan was the extent of the Easy Button's capabilities. Staples is testing how consumers react to it incorporating machine learning in its Easy Button that enables shoppers to press the button to order a product by voice, or to ask common questions, such as when an order will be delivered or the status of a return.
