-====================================
-Set-up Cash Control in Point of Sale
-====================================
-
-Cash control allows you to check the amount of the cashbox at the
-opening and closing. You can thus make sure no error has been made and
-that no cash is missing.
-
-Activate Cash Control
-=====================
-
-To activate the *Cash Control* feature, go to :menuselection:`Point
-of Sales --> Configuration --> Point of sale` and select your PoS
-interface.
-
-Under the payments category, you will find the cash control setting.

-
-In this example, you can see I want to have 275$ in various denomination
-at the opening and closing.
-
-When clicking on **Opening/Closing Values** you will be able to create
-those values.

-
-By default it will use the values you added before, but you can always
-modify it.
-
-Close a session
-===============
-
-When you want to close your session, you now have a *Set Closing
-Balance* button as well.
-
-You can then see the theoretical balance, the real closing balance (what
-you have just counted) and the difference between the two.

-
-If you use the *Take Money Out* option to take out your transactions
-for this session, you now have a zero-sum difference and the same
-closing balance as your opening balance. You cashbox is ready for the
-next session.
