+Connect an Ingenico Payment Terminal to your PoS
+================================================
+
+Connecting a payment terminal allows you to offer a fluid payment flow
+to your customers and ease the work of your cashiers.
+
+Please note that Ingenico is currently only available for customers in the
+Benelux.
+
+Configuration
+=============
+
+Connect a Payment Terminal
+--------------------------
+
+Connecting an Ingenico Payment Terminal to Odoo is a feature that
+requires an IoT Box. For more information on how to connect an IoT Box
+to your database, please refer to `this
+documentation <https://www.odoo.com/documentation/user/12.0/iot.html>`__.
+
+Once the IoT Box is up and running, you’ll need to link your payment
+terminal to your PoS. Open the Point of Sale app and go to Configuration
+> Point of Sale. Select a PoS, tick the IoT Box Device option and select
+your payment terminal.

+Configure the Lane/5000 for Ingenico BENELUX
+--------------------------------------------
+
+Click on the F button of the terminal, then go in the *PoS Menu* >
+settings menu and enter the settings password.
+
+Now, click on connexion change and TCP/IP. Type the IP of your *IoT
+Box* (you can find it on the form view of your IoT Box). Then, enter
+9000 as port. The terminal will restart. Once it is done, go on your
+*IoT Box* form in Odoo and verify that the terminal has been found.

+Ingenico setting.

+method for Ingenico, select the payment terminal option Ingenico, and
+select your payment terminal device.

+
+Pay with a payment terminal
+===========================
+
+In your *PoS interface*, when processing a payment, select a *Payment
+Method* using a payment terminal. Check that the amount in the tendered
+column is the one that has to be sent to the payment terminal and click
+on *Send*. When the payment is successful, the status will change to
+*Payment Successful*.
+

+
+If you want to cancel the payment request, click on cancel. You can
+still retry to send the payment request.
+
+If there is any issue with the payment terminal, you can still force the
+payment using the *Force Done*. This will allow you to validate the
+order in Odoo even if the connexion between the terminal and Odoo has
+issues.
+
+.. note::
+         This option will only be available if you received an error message
+         telling you the connexion failed.
+
+Once your payment is processed, on the payment record, you’ll find the
+type of card that has been used and the transaction ID.
