In order 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 configuration by client. Some options for your configuration include:
- Timeframe (default is 5 minutes)
- Last 4 of the credit card number, TransArmor Token match
- Customer Identifier match
- Station Identifier match
- Transaction Amount match
- Transaction Identifier match
Once the feature is activated, CP will start receiving messages when a transaction is flagged.
If the transaction is in-person, the chip-reader and the online prompt with 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 CP 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.
