CNN - MasterCard will approve purchases by scanning your face
CNN reports: "This fall, MasterCard will start experimenting with a new program: approving online purchases with a facial scan. At checkout, you'll be asked to hold up your phone and snap a photo. MasterCard's thinking? It's easier than remembering a password."

Comment: This is an interesting convergence of biometrics and purchase approval, it will be interesting to see if this catches on.
