Credit Pre-authorizations and Pre-authorization Completions
Credit card pre-authorization is a two-step process allowing you to verify the availability of unused credit,
to place a hold on the funds, and to charge the same or a different amount to the customer’s credit card
account (during pre-authorization completion).
When you perform a pre-authorization, the terminal obtains host approval and stores the approved pre-
authorization in the terminal memory (see page 24).
Depending on the type of business, there are two different ways you can use pre-authorizations:
• If your business is a restaurant or similar, use this method:
1. Perform a pre-authorization leaving the pre-authorization reference number blank. Enter the total
amount for the bill. The tip amount is unknown at this point.
2. The pre-authorization is stored in the terminal memory under a new pre-authorization reference
number assigned by the host.
3. Hand the receipt to the credit card customer and let them complete the tip line.
4. Perform a pre-authorization completion entering the reference number used in step 2 to retrieve
the original pre-authorization. The final transaction amount includes the tip.
5. After the pre-authorization completion is approved, the original pre-authorization is erased from
the terminal memory.
Note that when the above method is used, each pre-authorization completion refers to only one pre-
authorization. The pre-authorization completion receipt can be printed or not. See page 29 on how to
configure it.
• If your business is a hotel, a car rental, or any other requiring consecutive pre-authorizations, use this
method:
1. Perform a pre-authorization leaving the pre-authorization reference number blank. Enter the
amount for the first day of lodging or rent.
2. The pre-authorization is stored in the terminal memory under a new pre-authorization reference
number assigned by the host.
3. For each day that the service is provided, perform an additional pre-authorization using the same
reference number used in step 2 and enter the amount for the current day. The terminal adds the
current day amount to the pre-authorized total stored in the terminal memory. The receipt for a
consecutive pre-authorization includes the total for all pre-authorized amounts.
4. When you perform the pre-authorization completion you must enter the reference number used in
step 2 to retrieve the original pre-authorization and enter the final transaction amount, which
refers to the customer total.
5. After the pre-authorization completion is approved, the original pre-authorization is erased from
the terminal memory.
Note that when the above method is used, one pre-authorization completion may refer to one or
several pre-authorizations.
If your business requires consecutive pre-authorized amounts, you may not need the tip line printed
on the pre-authorization receipt. See page 29 on how to configure it.
Whichever method is used, you can generate a report containing the pre-authorizations (not yet
completed) currently stored in the terminal memory. See Incomplete Pre-authorization Inquiry
(page 77).

Prior to card entry, you may have selected the tender type (debit or credit) depending on the terminal
