Card Acceptor ID (CAID)
The Card Acceptor ID (CAID) is a unique identifier assigned to a merchant by their acquiring bank or payment processor. This identifier is used in transaction processing to uniquely identify the merchant and their location when the transaction takes place.
The CAID is critical for tracking and managing transactions. It helps ensure accurate routing and recording of payments, facilitate efficient dispute resolution, and maintain compliance with payment industry regulations. By associating each transaction with a specific merchant and location, the CAID aids in monitoring for fraudulent activity and helps generate detailed reports for business analytics and auditing.
