By default, less commonly used sales transactions (cash sale, force post, and swiping the payment card) require the Merchant password before they can be processed. You can choose whether or not to require the Merchant password, depending on your preference.
From the main screen, touch the Menu button.
Enter the merchant password and touch Confirm.
Scroll to the Configure application section.
Touch Passwords.
Scroll to the Require password for transactions section.
Enable the use of the Merchant password by toggling the following switches to the right:
Force post
Cash
Swipe
Disable the use of the Merchant password by toggling the previously listed switches to the left.
If you have more than one terminal, repeat steps 1 to 7 for each additional terminal where you want to set password usage for sales transactions.
