• In the event that it is necessary to include the customer's account number information that is not in IBAN format during the use of the QR code data organizations offered by the customer and the QR code data organizations offered in person-to-person payments, to use the "08: Account Number (Non-IBAN)" subfield added under the "61" coded "Application Template" field as a simple data object (data length: 2-30 variable, data type: special alphanumeric)
