Visa Compelling Evidence 3.0 (CE3.0) was introduced in 2023 to help merchants combat fraudulent chargebacks, costing them over $50 billion annually due to first-party fraud. CE3.0 provides merchants with a structured set of guidelines to dispute chargebacks automatically by requiring compelling evidence, such as IP addresses and device fingerprints, to prove that a transaction was genuine. This system specifically targets card-not-present (CNP) fraud by verifying if the same person made both the disputed and previous undisputed transactions. Merchants can benefit from the Order Insight program, which notifies them of potential disputes before they escalate to chargebacks, allowing for a timely response with CE3.0 evidence. Despite the potential variability of IP addresses, device fingerprints remain consistent across transactions, making them a reliable piece of evidence. The implementation of CE3.0 reduces the need for manual evidence compilation, which is both costly and less likely to result in a favorable outcome for merchants. Additionally, by maintaining a lower chargeback ratio, merchants can avoid higher transaction costs and comply with stringent requirements from programs like the Visa Acquirer Monitoring Program (VAMP).
