Amex’s Ingenious Blockchain Passport: Track Travel Memories You’ll Barely Notice Are Digital

The Blockchain State Team

09/19/2025

Travelers, get ready to ditch the ink stamps. American Express has rolled out a blockchain-based NFT passport feature that lets cardholders collect digital stamps of their global adventures. No more faded ink marks or dog-eared passport pages. Just tap your phone and boom—instant digital proof you actually made it to Paris. Or Bangkok. Or wherever your Amex card gets swiped.

The system works through the Amex Passport tool and their new Travel App. U.S. cardholders earn stamps automatically when making purchases abroad. Each stamp shows the country, date, and description of your trip. And yes, you can customize them with personal notes about that amazing pasta place or the museum that wasn’t worth the hype. Your memories, your way. These digital certificates of authenticity ensure each stamp is completely unique and impossible to duplicate.

Collect digital memories as you globe-trot—personalized country stamps for every swipe of your Amex card abroad.

These aren’t just any digital souvenirs. They’re ERC-721 NFTs minted on Base, an Ethereum Layer-2 solution. Fancy tech talk for: they’re secure, authentic, and permanent. Unlike your vacation photos that might disappear in your next phone crash. And before crypto-skeptics roll their eyes—these NFTs can’t be sold or transferred. No weird digital passport marketplace here.

Privacy concerns? Amex thought of that too. Your personal data stays off the blockchain. No names, account numbers, or that embarrassing story about what happened in Vegas. Just the bare travel facts on-chain, with your private notes stored securely elsewhere.

The whole system lives inside the Amex app. No separate crypto wallet or technical knowledge required. Just open your app, check your passport, and reminisce about that overpriced coffee in Milan. The enhanced Centurion Lounge Digital Waitlist now includes estimated wait times so you can better plan your airport lounging while collecting these digital stamps.

It’s a smart move by American Express, positioning them as innovators in the financial space. While other companies are still figuring out what blockchain even is, Amex is already using it to enhance their rewards program. According to research, 56% of respondents miss collecting physical passport stamps, making this digital alternative particularly timely. Will other travel brands follow suit? Probably. But for now, Amex cardholders get to be the cool kids with their digital travel memories. Not bad for a credit card perk.
