Friendly fraud (also called chargeback fraud) is an industry term for authorized cardholders who dispute seemingly legitimate charges to their credit cards. The authorized cardholder may file a chargeback on a legitimate charge for a few reasons: (1) they want to avoid paying for the order in question, (2) they may have forgotten they made the purchase, or (3) there may be another household member who made the purchase in their name, (4) They don’t recognize the merchant name appearing on their credit card bill. https://www.signifyd.com/resources/fraud-101/detection/friendly-fraud/
