Then it will defeat the purpose of anonymity. If you are worried about wrong typo leading to the fund going to different address then by all means always scan with a qr code. I usually get the recipient to screen capture the qr code and send to me to avoid mistakes in large fund transfer
Indeed this service is for manual transactions. For safety it's better if people get a double check option. At enterprises people have to handle loads of invoices. People can make mistakes by scanning the wrong QR code or other things may go wrong not mention any kind of fraud. Paying is peoples business after all.
I know it will defeat the purpose of anonymity. Though, I think business like to give in some anonymity to get more safety.
