Friendly fraud, also known as chargeback abuse or first-party fraud, occurs when customers dispute legitimate charges to receive refunds, resulting in significant financial losses for businesses and operational challenges due to chargeback fees. Despite being designed as a consumer protection mechanism, chargebacks are often exploited, with 75% estimated to be fraudulent and 35% of people admitting to engaging in such practices. To combat this issue, merchants are increasingly turning to advanced device identification solutions like Fingerprint, which analyzes a range of device attributes to create a unique and persistent identifier that links transactions to specific devices. This method provides strong evidence to dispute fraudulent claims by accurately tying them to the customer, even in cases of guest checkouts or when users attempt to conceal their activity through various methods. By recording visitor IDs alongside purchase data and building a comprehensive device activity profile, businesses can effectively counter friendly fraud and maintain their revenue streams.
