+The barcode functionality must be enabled in openBIS by a *lab manager*

+### Barcodes for individual samples
 
+When a sample is registered, a barcode is automatically generated by
+openBIS. This is found in the **Identification info** section, as shown
+below.
 
+![](img/Default-sample-barcode-1.png)
+
+This barcode can be printed and the label can be added to the vial
+containing the sample. The option to print the barcode is under the 
+**More..** menu
+
+![](img/Default-barcode-print.png)
+
+If a sample already has it own barcode, it is possible to scan this with
+a scanner or the camera of a mobile device and assign it to the sample.
+This can be done after registration of a sample, with the **Custom
+Barcode Update** option under the **More..** drop down.
+
+![](img/custom-barcode-update-1.png)
+
+The custom barcode will appear in the *Identification Info*. If a custom
+barcode is registered, the print function shown above will print the
+custom barcode, instead of the default one.
+
+### Generate batches of barcodes
+
+In some cases there is the need to generate several barcodes that can be
+later on assigned to samples registered in openBIS.
+
+To generate new barcodes, go to the **Barcodes Generator** in the main
+menu under **Utilities**.
+
+![](img/Barcode-generator-1024x466.png)
+
+Users can select:
+
+1.  The type of barcode to generate:
+    1.  *Code 128*
+    2.  *QR Code*
+    3.  *Micro QR code*
+2.  The number of barcodes to generate
+3.  The layout:
+    1.  *Split*: one barcode per page
+    2.  *Continuous*: several barcodes in one page
+4.  The width of the barcode
+5.  The length of the barcode
+
+After selecting the desired parameters, click the **Generate Custom
+Barcodes** button.
+
+To print the barcodes use the **print icon** on the form, next to
+**Generate Custom Barcodes**. These barcodes can be printed on labels to
+be attached to vials. When the samples are registered in openBIS, these
+barcodes can be scanned and assigned to the samples as explained above.
+
+### Scan barcodes from mobile devices
+
+It is also possible to scan barcodes and QR codes using the scan button
+on top of the main menu, as shown below. In this way, you can scan a
+barcode or QR code already associated with an entry and this will open
+the entry page in openBIS. You can use a scanner or the camera of a
+mobile device. The selection you make is saved.

 ## Scanners
 
 There are several manufacturers of barcode scanners. In most cases
 scanners act as a keyboard for the computer, so when the barcode scanner
 scans a barcode it will type whatever has been scanned.

 ### Scanner Configuration
 
 The scanner keyboard layout should be the same as the computer used. If
 not this could cause problems if there are any special characters.
