There may be situations where you need to obtain an authorization for a credit card sale directly from the card issuer. In such a case, you must manually enter the authorization code provided by the issuer into the terminal to complete the transaction.
Touch Operations and touch Force post from the menu.
Enter the Merchant password and then touch Confirm.
NOTE: If you have previously disabled password protection for force post transactions, the terminal will not ask for the password.
Using the number pad, enter the Authorization code provided by the card issuer and touch Confirm.
Tap, insert, or swipe the payment card.
After confirming the force post transaction, the terminal prints the merchant copy of the transaction receipt. To print the customer copy, touch Print receipt or touch No receipt if no customer copy is requested.
