Anyone who regularly travels outside the U.S. is likely aware of the growing significance of mobile on shopping activities everywhere. While PC online shoppers in the U.S. are among the top countries by percentage, those buying via smartphone and laptop actually lag other countries, based on new research.

Mobile innovation can sometimes transform a process while not disrupting things along the way. A couple of years ago, a California startup named Endorse created what seemed to be a path of least consumer resistance for mobile coupons. The well-funded startup challenged the age-old concept of coupons by creating an app that allowed consumers to take a photo of their grocery shopping receipt, upload it to Endorse and receive credit that could be redeemed for cash, which was sent by check or via PayPal.
