Fraud Reporting (Mastercard)

The Mastercard Fraud and Loss Database (previously System to Avoid Fraud Effectively (SAFE)) is a Mastercard repository of fraud transactions submitted by issuers. It is used for reporting, monitoring, and combating card fraud.

Mastercard requires issuers to report to the Fraud and Loss Database at the customer ID level all Mastercard transactions that the issuer considers to be fraudulent, even if the corresponding accounts are not closed or marked as fraud.

For issuers, Fraud and Loss Database reporting can be accessed directly via Mastercard Connect.

For other Thredd customers, Thredd provides an option on Smart Client to enable you to easily report a transaction as fraud to Mastercard. Thredd sends a message to Mastercom using the MasterCom API.
