Debit Pre-dial enables the terminal to begin dialing the host before data is entered by the cardholder during a Purchase, as a way to speed up dial transactions. By default this feature is enabled.
Note: This feature is not applicable to merchants using Ethernet (IP) communications.
Note: Do not enable this feature if you are using multiple transaction features such as tip processing and cashback, as it will initiate multiple calls to the host, thereby slowing down the overall transaction.
Set the Debit Predial parameter to On.
Set the Debit Predial parameter to Off.
