QR for payment by SMS

Today for the first time in my life I paid for the service via SMS, and in order not to press the inconvenient, small buttons of the smartphone, I simply opened qrcode.kaywa.com and filled in the required fields on the computer, then fed the picture to the barcode scanner on the phone - and received a ready SMS (with the filled in number and the text) - it was necessary only to click "send".
So, why don't you, gentlemen accepting payment via SMS, simplify the user's life and not add a small picture next to the payment information? The benefit is done very simply - for example, the code at the link chart.apis.google.com/.../ generates a message to number 01 with the text abcdef123. And there are ready-made solutions for generating QR codes for popular programming languages, if you don’t want to depend on Google.
Implementing is not difficult (except to enter into the design), and the user is pleased.
