+ Alipay Payments in POS
+========================
+
+The module implements following payment workflows
+
+Barcode Payment
+---------------
+
+* Cashier creates order and scan user's QR in user's Alipay mobile app
+
+  * scanning can be done via Mobile Phone camera (``pos_mobile`` module is recommended)
+  * scanning can be done via usb scanner
+  * scanning can be done via usb scanner attached to PosBox
+
+* User's receives order information and authorise fund transferring
+* Cashier gets payment confirmation in POS
+
+QR Code Payment
+---------------
+
+* Cashier clicks a button to get one-time url and shows it to Buyer as a QR Code
+
+  * QR can be shown in POS
+  * QR can be shown in Mobile POS (``pos_mobile`` module is recommended)
+  * QR can be shown in Customer screen
+
+* Buyer scans to finish the transaction.
+* Cashier gets payment confirmation in POS
+
+Debugging
+=========
+
+Scanning
+--------
+
+If you don't have camera or scanner, you can executing following code in browser console to simulate scanning::
+
+    odoo.__DEBUG__.services['web.core'].bus.trigger('qr_scanned', '28763443825664394');
+
+Customer Screen
+---------------
+
+To emulate Customer screen do as following:
+
+* run another odoo on a different port, say ``9069``, workers 1,  extra *server wide modules*, i.e. use ``--workers=1 --load=web,hw_proxy,hw_posbox_homepage,hw_screen``
+* open page at your browser: http://localhost:9069/point_of_sale/display -- you must see message ``POSBox Client display``
+* at POS' Settings activate ``[x] PosBox``, activate ``[x] Customer Display`` and set **IP Address** to ``localhost:9069``
+* Now just open POS
+
+Roadmap
+=======
+
+* TODO: In sake of UX, we need to add ``alipay_order_id`` reference to ``account.bank.statement.line``
