Fraud protection

Use your Card with confidence anywhere in the world

Intelligent security

Intelligent security is the sophisticated machine learning technology that keeps you safe every time you use your Amex card.

It understands the patterns in your spending and makes smart, split-second decisions that protect you from fraud.

Secure payment system

In addition, whatever you buy online or in-store, at home or around the world, your transaction is processed through our secure payment system. Because, unlike other cards, our transactions usually involve only three parties: you, the merchant and us. Which means we‘re better placed to spot issues as soon as they arise and will aim to resolve them faster.

See how else we protect you.
