No cash, credit card, or smartphone? No problem. Just smile to pay. That’s now possible, in China, thanks to tech giant Alibaba’s new facial recognition system, live at a KFC restaurant in Hangzhou. After selecting a meal (healthy options available), customers can authenticate payment by having their faces scanned for one or two seconds, and cross-referenced with a government database. Currently, they also punch in their mobile number for security. Meanwhile, shareholders in Alibaba also have reason to smile. The shares, which are listed on the New York Stock Exchange, are up 91.5% year to date.
