+============================
+Add EPC QR Codes to invoices
+============================
+European Payments Council Quick Response Code, 
+or **EPC QR Code**, are two-dimensional barcodes 
+that customers can scan with their **mobile banking 
+applications** to initiate a **SEPA Credit Transfer
+(SCT)**, and pay their invoices instantly.
+
+In addition to bringing ease of use and speed, 
+it greatly reduces typing errors that would potentially 
+make for payment issues. 
+
+.. note::
+   This feature is only available in several European 
+   countries such as Austria, Belgium, Finland, Germany, 
+   and The Netherlands.
+   
+Configuration
+=============
+Go to :menuselection:`Accounting --> Configuration --> Settings` 
+and activate the **SEPA QR Code** feature.

+-------------------------------------
+Make sure that your *Bank Account* is correctly configured 
+on Odoo with your IBAN and BIC.
+
+To do so, go to :menuselection:`Accounting --> Configuration 
+--> Journals`, open your *bank journal*, then fill out the 
+*Bank Account* and *Bank* under the *Bank Account* tab.

+
+Issue Invoices with EPC QR Codes
+================================
+EPC QR Codes are added automatically to your invoices, as 
+long as you issue them to customers that are located in a 
+country where this feature is available.
+
+Go to :menuselection:`Accounting --> Customers --> Invoices`, 
+and create a new invoice. 
+
+Before posting it, open the *Other Info* tab. Odoo automatically 
+fills out the *Bank Account* field with your IBAN.
+
+Make sure that the account indicated is the one you want to use to 
+receive your customer’s payment as Odoo uses this field to generate 
+the EPC QR Code.
+
+.. image:: media/epc_qr_code03.png
+   :align: center
+   
+.. tip::
+   If you want to issue an invoice without an EPC QR Code, 
+   remove the IBAN indicated in the *Bank Account* field, 
+   under the *Other Info* tab of the invoice.
