Tender a Guest Check
Introduction
❏ Secondary authorization difference percentage. The
maximum percentage amount that the payment amount can
exceed previous authorizations without requiring another
credit authorization.
For example, a credit card is authorized for $10.00. The
secondary authorization difference percentage is 10%. When
the final bill is presented and tip is added, the payment
amount is $12.00. Because $12.00 is 20% more than the
authorized amount, and the maximum difference allowed is
only 10%, a secondary authorization is required before the
credit card can be tendered.
Credit Finalization
A credit finalization ensures that a sufficient amount has been
authorized, and then closes the check. You can only perform a
finalization if a credit authorization has been done. To finalize,
you press the [Credit Finalize] key.
Note
Keep in mind that many of these limits work together.
For more information on credit authorization limits,
refer to the 3700 Feature Reference Manual.
