The stamps can be customised to commemorate specific trip highlights, and while they are minted as NFTs, they are non-transferable and do not contain personal data on the public blockchain, distinguishing them from the speculative crypto market.
American Express has launched a new program, Amex Passport, which offers customers blockchain-based stamps as digital keepsakes of their travels. The initiative provides a permanent, digital alternative to traditional passport stamps, which have become less common.
According to a company statement, each travel stamp is stored as an ERC-721 non-fungible token (NFT) on the Ethereum layer-2 network, Base. This process is intended to preserve a customer’s travel history and memories on a decentralised ledger.
Luke Gebb, Executive Vice President of Amex Digital Labs, stated that the program aims to help travelers “relive their favorite trips” in a digital format.
Customise it Your Way
To that regard, the digital stamps can be customised by users to commemorate specific trip highlights, such as a particular attraction, a notable meal, or a favorite activity. While the stamps are minted as NFTs, they are explicitly designed as non-transferable, meaning they cannot be sold or traded.
This design choice separates the program from the speculative cryptocurrency market, and the company clarified that the stamps do not contain personal or sensitive trip data on the public blockchain.
Evidently, the eligibility for Amex Passport is limited to holders of a US American Express consumer card who have linked their card to an online account. The program automatically generates stamps for qualifying international trips.
