The QR scanner is the feature that helps you to make a payment in a jiffy. You
don’t need to enter details like the mobile number of the recipient. All you have
to do is to scan a code and then make a payment. But if you’re unable to do
that, then check the internet connection and the camera for a possible problem
source. But if you believe that there is some other problem, then feel free to give
a call at the Cash App number for assistance.
