Uber CEO Dara Khosrowshahi has confirmed that the firm is to roll out a selfie style feature on its app so that drivers can verify some riders are wearing face masks.
The selfie feature will be used in the US and Canada, and is set to be introduced by the end of September to run inline with driver procedure.
The firm has said other regions after that, will look for a mask-like covering over the mouth and nose.
Currently, drivers must take a mask selfie each day before starting work.
If the scanner does not detect the driver is wearing a mask they are blocked from using the app to pick up passengers.
The driver policy was introduced on 18 May and then extended indefinitely due to the ongoing pandemic, requiring both drivers and riders to wear a face covering at all times during a ride, but riders didn't have to take a picture to confirm they were wearing one.
Drivers and riders are able to cancel a trip without charge if they report the other party is not wearing a mask. Failure to comply can lead to account deactivation.
In a tweet, Uber boss Dara Khosrowshahi said "Accountability is a two way street. That's why we're extending mask verification to riders, in addition to drivers. We're all in this together, so let's help protect one another."
