American Express takes several measures to prevent credit card fraud:

1. Advanced Fraud Detection: American Express employs advanced algorithms and analytics to detect fraudulent patterns and unusual transactions. They continuously monitor card activity in real-time to identify suspicious transactions.
2. EMV Chip Technology: American Express has implemented EMV (Europay, Mastercard, and Visa) chip technology in its credit cards. These chips create a unique code for every transaction, making it extremely difficult for fraudsters to clone cards.
3. Two-Factor Authentication: American Express uses two-factor authentication methods, such as dynamic OTP (One-Time Password) or biometric verification, for secure online transactions. These additional layers of verification increase security and reduce the risk of unauthorized use.
4. SafeKey: American Express offers a program called SafeKey, which is a secure online authentication process for cardholders. SafeKey adds an extra layer of security by validating the cardholder's identity during online purchases.
5. 24/7 Monitoring: American Express has a dedicated team that continuously monitors card activity for potential fraud. They use sophisticated systems to identify suspicious transactions or account activities, enabling them to take immediate action to prevent fraud.
6. Liability Protection: American Express provides its cardholders with enhanced liability protection against unauthorized charges. If a cardholder reports fraudulent activity promptly, they are generally not held responsible for fraudulent charges.
7. Secure Online Shopping: American Express provides additional security measures for online shopping, such as virtual card numbers and ShopSafe feature. Virtual card numbers allow users to generate temporary card numbers for online transactions, reducing the risk of exposing their actual card details. ShopSafe generates unique card numbers for each online merchant, providing an added layer of security.
8. Education and Awareness: American Express educates its cardholders about the latest fraud trends and prevention techniques. They provide resources, including tips and guidance, to help cardholders protect themselves from fraud.

It's important to note that these measures are subject to change, as American Express continuously improves its security systems and adapts to new fraud techniques.
