Amazon May Let You Pay With a Wink and a Nod

Amazon has applied for a patent for selfie-based authentication for online purchases, according to a patent application published last week. Using the technology, a prospective purchaser would take a selfie, and the image would be authenticated against an image database using facial recognition software. The buyer then would perform a requested action, such as winking, to verify that the image is of a live human being. That would trigger completion of the transaction.
