description: 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.
