American Express Enhanced Authorization (EA)

American Express Enhanced Authorization (EA) is a fraud prevention tool that helps protect cardholders and merchants from unauthorized transactions. EA uses advanced algorithms and machine learning to analyze transaction patterns and detect suspicious activity. By passing additional transaction data elements at the time of authorization, this system enables American Express to provide real-time authorization decisions, allowing them to quickly identify and block potentially fraudulent transactions before they are approved.
