Velocity controls are settings that determine transaction thresholds for a particular Merchant. These settings can be accessed by logging into the Realtime Payment Manager and navigating to Admin -> Terminals, and then clicking on the appropriate Merchant name in the list that comes up.
The following Velocity controls are available:
Minimum Sale $
Any transaction that falls below the amount defined for this setting will not be processed.
Maximum Sale $
Any transaction that exceeds the amount defined for this setting will not be processed.
Day Volume $
The total dollar amount of all transactions processed through a given Merchant in a day is compared against this value. If a transaction will put the total dollar amount of all transactions for the day above this threshold, the transaction will not be processed.
Day Card Usage $
This setting determines the total dollar amount permitted to be charged against a single card in a day.
