Alibaba Wants to Let You Use 'Selfies' to Confirm Payment

Someday soon, buying items online may require you to smile before paying, no matter how high the price. At least, this is where Alibaba Group Holdings Inc.'s new technology seeks to lead us. Earlier this week, Alibaba Founder and Chairman Jack Ma unveiled the company's "Smile to Pay" system, which will allow users to confirm their identity by face-recognition technology rather than with passwords or other digital tokens. Ma showed off the new system in a presentation at the opening of the CeBit technology conference in Hanover, Germany.
