Celebrating travel with blockchain-based keepsakes

The newly introduced Amex Passport stamps exist as unique ERC-721 non-fungible tokens minted on Ethereum’s layer-2 Base blockchain. These digital stamps store basic travel information such as the country or region visited, the date of the visit, and a customizable description highlighting memorable experiences like a favourite meal, activity, or landmark. Amex Digital Labs Executive Vice President Luke Gebb emphasized that as traditional physical passport stamps become less common, the Amex Passport offers a novel way for travellers to relive and celebrate their journeys.

Customers holding a U.S. American Express consumer card linked to their online account can automatically receive NFT stamps for qualifying trips booked through Amex up to two years ago. While the NFTs enhance digital sharing and storage, the stamps are non-transferable and contain no sensitive personal or trip-specific data accessible to others.

Growing demand and crypto adoption in travel

This initiative taps into strong consumer interest in digital mementos from travel, with a recent Amex survey revealing that 73% of respondents desire more digital ways to commemorate trips. In comparison, 56% miss the traditional passport stamp experience upon entering new countries. The broader crypto travel space is also evolving; platforms like Travala now support crypto payments for millions of hotels, and data indicates that about 14% of crypto transactions in 2024 relate to travel and hospitality.

American Express’s launch of blockchain-based NFT stamps reflects a trend of leveraging public blockchains for secure, decentralized storage of customer data beyond conventional centralized systems, positioning itself at the intersection of finance, travel, and emerging digital technologies.

Notably, August saw a 27% surge in Metaverse NFT sales, indicating cautious yet renewed interest in virtual worlds. Despite a slight decrease in dollar volume, the increase in transaction numbers suggests users are gradually returning to platforms such as Sandbox and Decentraland.
