Payment fraud refers to a broad range of illegal activities in which criminals use stolen, counterfeit, or unauthorized payment information to make purchases or transfer funds without the legitimate cardholder’s consent. This includes credit card fraud, identity theft, account takeover, friendly fraud (i.e., chargeback abuse), and more complex schemes involving synthetic identities or social engineering tactics. Payment fraud costs businesses billions of dollars each year through direct financial losses, chargeback penalties, increased processing fees, and reputational damage that can erode customer trust and long-term revenue.
Modern payment fraud prevention relies on multi-layered security strategies that combine machine learning algorithms, behavioral analytics, device fingerprinting, and real-time transaction monitoring. Companies use fraud detection systems that assess transaction patterns, verify customer identities, and flag suspicious activities, all while minimizing false positives that could block legitimate customers.
Effective fraud prevention requires a balance between security and user experience—offering strong protection without introducing friction that drives away genuine users. Common tools and practices include tokenization, 3D Secure authentication, address verification systems (AVS), velocity checks, and comprehensive staff training to recognize fraud indicators and respond appropriately.
