Level III credit card processing transactions require sending more data than a Level I or Level II transactions at the time of the transaction. Specific line item details are required to qualify for Level III transaction rates. A transaction can only be reviewed and accepted for Level III by TSYS if the card was scanned or a vaulted card was used. A keyed in card will not be accepted by TSYS for Level III processing.
If your transactions qualify for Level III processing:
- Navigate to File > Customer Master.
- In the Setup section, click the Credit tab.
- In Credit Options, select the Level Three Credit Card check box.
- Click Save.
Level 3 information is sent to TSYS with transactions.
