Uber's "Real-Time ID" Feature: In order to prevent fraud where different people may be sharing and driving the same car (and hence Uber account), Uber has been employing a feature called "Real-Time ID Check." This is a mechanism built into the Uber Driver app where drivers need to validate their identify by taking selfies of themselves. Then the facial-recognition feature will identify the driver and determine if he is who he say he is. They can be prompted at a beginning of a shift or asked during a shift.
