Mastercard Chargeback Reason Code 4870 Chip Liability Shift

Table of Contents

What Does Mastercard 4870 Chargeback Reason Code Mean? Mastercard chargeback reason code 4870, or "Chip Liability Shift," shows up when a transaction is processed using the magnetic stripe instead of the emv chip, and the cardholder disputes it as fraudulent. In this case, the merchant is on the hook for the payment because they didn’t use the more secure chip technology. To avoid this, merchants should make sure they’re using EMV chip-enabled terminals and always process transactions with the chip. This helps keep things secure and cuts down on fraud-related chargebacks.
