We know that Walmart has been offering deals on smartphones and even discounting the iPhone, now they are starting a program where customers can use their iPhones to check out and pay at self-service lanes.
Walmart touts it as a faster way to shop and save by scanning items with iPhones and putting them in bags in the cart while shopping.
Over half of Walmart shoppers use smartphones, the new service "Scan & Go" is designed to get shoppers through the self-service line quickly.
