Overview

• Amex Passport is live in the Amex Travel app, with on-chain explorers showing more than 20,000 travel stamps issued soon after launch.
• Eligibility is limited to U.S. consumer cardholders, with stamps triggered by in-person purchases in 130+ countries and retroactive additions for up to two years.
• Each stamp is an ERC-721 token on Coinbase’s Base that records the country or region visited, the date, and a short trip description without storing personal data.
• Fireblocks provides Wallet-as-a-Service infrastructure underpinning the feature inside the Amex Travel app.
• The revamped app adds travel tools including customizable, shareable stamp images and estimated Centurion Lounge wait times, with iOS rollout set for September 18 and Android to follow.
