For a duplicate transaction to be denied, you must have this feature turned on. You can turn it on by contacting Tempus. Tempus offers flexible configurations. Some options for your configuration include:
Timeframe (default is 5 minutes)
The last 4 of the credit card numbers, TransArmor Token match
Customer Identifier match
Station Identifier match
Transaction Amount match
Transaction Identifier match
Once the feature is activated, CivicPlus will start receiving messages when a transaction is flagged.
If the transaction is in-person, the chip reader and the online prompt will both show a Duplicate Transaction message.
If the transaction is online, a message will show and the user can try again. However, whether or not additional attempts will be successful will depend solely on the rules you have in place with Tempus.
To verify if a transaction was a duplicate, navigate to CivicPlus Pay. The activity log will show a Fail and a response of Duplicate Transaction.
You can also double-check the raw response to see the exact message that we received from Tempus.
If you believe that a transaction was wrongly flagged as a duplicate, you will want to review your rules and reach out to Tempus’ customer support.
