The POS uses HTML5 Local Storage to hold all the critical information that it needs in order to operate. This includes product data and clerk data.


When working off-line, a will appear in the top bar of the POS to alert you, do not refresh or backstep out of the POS as you will be unable to log back in. 


⚠ CAUTION! You should avoid using Clear history, Deleting cookies or similar functions which clear your browser cache. Doing this will wipe the local storage, and any settings which are held there. Browsers can be configured to automatically clear these on browser exit, and other third party applications can also "clean" your browser These types of tasks should not be performed.


⚠CAUTION: If you clear the local storage (Through clearing browser cache, running clean-up tools, deleting cookies etc) whilst you are off-line, then you will not be able to start the POS.


You may however be asked to clear the cache by a member of the K3 support team. 


NOTE: Any sales completed using the 'default' connector will not show on the Z read. The 'default' connector is available whilst offline to enable sales to be completed.
