Mega e-commerce company Amazon has recently filed a patent for the "Pay By Selfie" technology, which allows customers to take a selfie picture or video to authorize payments as opposed to typing in a password.

The "Pay By Selfie" method is aimed to make it safer for customers to shop online by relying on photo identification as opposed to a password, which can often be hard to remember and can become a dangerous situation if lost or stolen.

According to the patent, the camera “can prompt the user to perform certain actions, motions, or gestures, such as to smile, blink, or tilt his or her head," reports Hypebeast. These actions prove to the computer that it is indeed the person and not someone else holding up a photo or video. 

The selfie based tech may not be appealing to all but it is sure to entice many as worded passwords become outdated. According to re/code, Alibaba founder Jack Ma proposed a similar idea last year at the CeBit conference and even gave a demonstration. 

Furthermore, CNN Money reports MasterCard is hoping to ditch the old-fashioned password and use selfies to approve online purchases as well.
