I read about Mastercard developing an app that uses facial recognition to authenticate transactions. Wouldn't be surprised if they store the image for future dispute resolution purposes. It's a pretty strong proof that you authorised the purchase (unless you have an identical twin, or parents with dominant genes
) but it just seems really creepy to be letting an app phone home your face. Then again, gen-Y don't seem to care about things like that.
One way the app ensures it's a live person and not a photo or loop is by asking you to smile at a certain point. The Mastercard equivalent of asking a cute girl on an anonymous webcam chat site to wave to prove you're not being shown a recording.
