4866 Fraud-Chip Card Counterfeit Transaction
Details
This code is used when a cardholder disputes a transaction, alleging that a counterfeit chip card was used fraudulently. This typically occurs when a merchant processes a chip card transaction without adhering to EMV standards, such as by using a magnetic stripe instead of a chip reader, leading to potential liability for counterfeit fraud.
