In Austria/Europe, government agencies and other organizations offer the option of transferring payment via QR code scan.
I would like a field where I can enter my bank details, and the QR code field itself would be pre-filled with the account number, ticket ID, and custom fields.
The customer receives the invoice and can transfer the amount directly by scanning the code, without having to enter any data themselves!

An advantage for the operator is that there are no bank fees for the transfer.
Attached is an example – a screenshot and link:

Thank you in advance!
