Apple pay did not work in walgreens
I have used it before, but it did not work in a walgreens. Is there a way to test sensor if it is transmitting?

You need to ask CVS to update their machines but there is not really a way to check your phone unless you go to another terminal that you know is working correctly. Apple can do a hardware diagnostics but we as fellow users cannot. Force reboot your device to see if that resolves anything.
