Method and apparatus for reducing fraudulent credit transactions by requiring merchant return of multi-digit authorization codes

Processes for reducing fraudulent credit transactions, including financial (e.g., credit, charge, debit, etc.) card transactions, are introduced, in which merchants receive multi-digit authorization codes from a credit provider (e.g., a customer transaction account card user) with all approved transactions. To guarantee payment, all merchants are required to later resubmit the multi-digit authorization code with every record of charge, regardless of dollar amount, as verification that an authorization was obtained. Merchants that fail to provide any authorization code, or an incorrect authorization code, will be subject to a chargeback for non-compliance.
