As international travel becomes increasingly digital, physical passport stamps are steadily disappearing, prompting American Express to look for new ways customers can preserve memories of trips abroad. Many countries have shifted to electronic gates and digital entry records in place of physical stamping, which has left fewer tangible souvenirs of international trips.

A survey commissioned by American Express found that 73% of adults wanted additional ways to digitally commemorate their international travels. That finding inspired an internal idea: transforming eligible card transactions made during trips into virtual collectible stamps that customers could access through the American Express mobile app.

The concept grew into Amex Passport, a digital travel experience built with blockchain technology. The program uses blockchain to create and track collectible travel stamps based on customers' card activity, and the collection has become one of the largest nonfungible token collections on Base, a blockchain network. Base is an Ethereum-layer-2 network developed by Coinbase, and its adoption by a major payments company reflects how established financial brands have increasingly experimented with consumer blockchain applications.

Following customer feedback, American Express has expanded the program so cardholders can generate digital stamps for qualifying trips dating back to 2019. The change allows customers to build a broader digital record of their international travel history instead of being limited to more recent journeys.

Digital Labs Turns Ideas Into Customer Products

Amex Passport was first introduced through an in-house testing environment where customers could try experimental features. Its development reflects a broader innovation strategy at American Express, which has been exploring emerging technologies including blockchain and artificial intelligence. This mirrors a wider trend among large financial institutions, which have set up internal innovation units to pilot emerging technologies before committing to full-scale deployment.

The company's Digital Labs, a specialized innovation unit of roughly 120 employees, works with teams across the organization to turn promising concepts into customer-facing pilots. Ideas can originate through internal initiatives and are then evaluated, developed, and tested before potentially moving into wider deployment.

American Express received more than 110 ideas through its annual Innovation Challenge in 2025. The strongest concepts were then taken through a structured development process involving Digital Labs and other teams.

Amex Passport shows how American Express is using blockchain to convert ordinary card transactions into digital travel collectibles, giving customers a new way to preserve and revisit their international travel experiences.

The company's approach emphasizes testing products in real-world settings rather than developing technology purely as a theoretical exercise. Executive Vice President and Global Head of Innovation Luke Gebb has described the company's innovation process as centered on taking ideas to market and learning from the results.

Cloud Data Platform Supports AI and Fraud Detection

American Express has also been investing in technology infrastructure that supports applications beyond customer-facing products. One example is Lumi, a centralized, cloud-based data platform developed to support several areas of the company's operations.

Lumi is being used to improve fraud detection and enhance customer support capabilities, while also providing infrastructure for additional artificial intelligence experimentation. The platform forms part of a wider effort to use data and emerging technologies across the company. Fraud detection has become one of the most common enterprise applications of machine learning in financial services, where large transaction datasets are used to identify suspicious activity.

American Express has explored hundreds of potential artificial intelligence applications, reflecting the growing role of automation and data-driven systems in financial services.

The company's innovation program combines customer-facing experiments such as Amex Passport with large-scale technology initiatives designed to strengthen fraud prevention, customer service, and artificial intelligence development.

Innovation Efforts Expand Amid Credit Card Competition

American Express has established several internal programs to encourage employees to develop and test new ideas, including innovation awards and a global hackathon that attracted more than 400 teams.

The company also launched Amex U in March 2026, a training platform intended to support employee development and technology-focused learning. These programs are designed to broaden participation in innovation beyond specialized technology teams.

The strategy comes as competition remains intense across the credit card industry, where companies are seeking new ways to differentiate customer experiences while improving digital services.

For American Express, Amex Passport illustrates how emerging technologies can be applied to relatively familiar financial products. Rather than using blockchain solely for financial transactions, the company has incorporated it into a customer engagement experience centered on travel.

The expansion to trips dating back to 2019 also indicates that customer feedback is shaping how the initiative evolves. By combining transaction data, blockchain-based collectibles, and mobile technology, American Express is seeking to create a digital travel record that extends the role of its payment cards beyond purchases and into the preservation of travel memories.
