Credit Card Glossary: Terms and Definitions
A transaction identifier is a unique 15-character value that Visa assigns to each transaction and returns to the acquirer in the authorization response. Visa uses this value to maintain an audit trail throughout the life cycle of the transaction and all related transactions, such as reversals, adjustments, confirmations and charge-backs.
