Mastercard wants to let you buy stuff with your face

Leave your plastic at home — all you need to make purchases in a new pilot program from Mastercard is your face.

To buy something, simply smile or wave at a camera equipped with a biometric reader, according to the company, which touts the advantage of not having to pull out your pocketbook or phone to make payment. 

Mastercard's "Biometric Checkout Program," which uses the same kind of technology that allows Apple iPhone owners to unlock their devices with their face or fingerprints, is designed for use at retailers. Individuals who wish to test the technology must first enroll in the program in stores or through an app at home.
