This guide will help you find the GPoS Licence code on a till. There are a few different ways to find the code but this is the easiest

You need a button called System Operation on your till. We would suggest putting it on your manager or End of Day screen and not one in everyday use.  The key to add is found under the System Keys list of buttons  Using the Touch Screen Layout (How to Use)

Once you have that button you enter 9961217 on the numeric keypad and then press the 'System Operation' button.

The serial number will then be shown on the till screen as per below. The first 8 digits are your licence code
