It’s super clean. I don’t know how you can hide root though .
I think safaricom should force supermarkets to use QR scanning to pay for goods. I have used it many times and it is super fast; faster than giving out your number to trigger popup (pale Shoprite ), keying in “buy goods” digits , and handling cash (who does that nowadays? ).
I don’t know why retailers don’t embrace this method considering how clean it is and can be used by anyone with a camera (any smartphone basically). It sucks having to tell the cashier to show you the QR code
