 Set up your hardware
-====================
+====================
+
+Getting started with barcode scanning in Odoo is fairly easy. Yet, a
+good user experience relies on an appropriate hardware setup. This guide
+will help you through the task of choosing and configuring the barcode
+scanner.
+
+Find the barcode scanner that suits your needs
+==============================================
+
+The 3 recommended type of barcode scanners to work with the Odoo
+**Inventory** and **Barcode Scanning** apps are the **USB scanner**, **the bluetooth
+scanner** and the **mobile computer scanner**.

+
+-   If you scan products at a computer location, the **USB scanner** is the
+    way to go. Simply plug it in the computer to start scanning. Just
+    make sure when you buy it that the scanner is compatible with
+    your keyboard layout or can be configured to be so.
+
+-   The **bluetooth scanner** can be paired with a smartphone or a tablet and
+    is a good choice if you want to be mobile but don’t need a big
+    investment. An approach is to log in Odoo on you smartphone, pair
+    the bluetooth scanner with the smartphone and work in the
+    warehouse with always the possibility to check your smartphone
+    from time to time and use the software ‘manually’.
+
+-   For heavy use, the **mobile computer scanner** is the handiest solution.
+    It consists in a small computer with a built-in barcode scanner.
+    This one can turn out to be a very productive solution, however
+    you need to make sure that is is capable of running Odoo smoothy.
+    The most recent models using Android + Google Chrome or Windows +
+    Internet Explorer Mobile should do the job. However, due to the
+    variety of models and configurations on the market, it is
+    essential to test it first.
+
+Configure your barcode scanner
+==============================
+
+Keyboard layout
+---------------
+

+    :align: center
+
+An USB barcode scanner needs to be configured to use the same keyboard
+layout as your operating system. Otherwise, your scanner won't translate
+characters correctly (replacing a 'A' with a 'Q' for example). Most
+scanners are configured by scanning the appropriate barcode in the user
+manual.
+
+Automatic carriage return
+-------------------------
+
+By default, Odoo has a 50 milliseconds delay between each successive
+scan (it helps avoid accidental double scanning). If you want to
+suppress this delay, you can configure your scanner to insert a carriage
+return at the end of each barcode. This is usually the default
+configuration and can be explicitly configured by scanning a specific
+barcode in the user manual ('CR suffix ON', 'Apply Enter for suffix',
+etc.).
