Fraud Monitoring

Halyard Pay monitors merchant fraud activity and leverages Mastercard's MATCH system for enhanced fraud risk assessment on merchants processed through our platform.

When this policy applies

This policy applies to all merchants processed by Halyard Pay where Mastercard is the applicable network, covering both card-present and card-not-present transactions.

Required actions

1. Compute the merchant's rolling fraud-to-sales ratio each calendar month.

2. If the ratio meets or exceeds 1.5% and the fraud count reaches at least 100 transactions in that month, escalate the merchant account to human review immediately.

3. Utilize Mastercard's MATCH system data focusing on principal owners only, as per the updated Mastercard SPME guidelines. Do not consider associate owners or Service Provider names in fraud assessments.

4. After accessing MATCH data, conduct a risk assessment to determine whether further investigation or additional measures are warranted.

5. Implement a process to acknowledge and respond to Mastercard notifications that a merchant has been preliminarily identified as Questionable, as per SPME §8.4.4. This includes monitoring email communications sent to the Acquirer's Security Contact and preparing any supplemental information for contest submissions within the required 15 calendar-day period.

6. Notify the acquiring compliance officer and document the case ID with supporting transaction data.

6. 7. Track case progress until the account returns to threshold compliance or is terminated.
