American Express has introduced Ethereum-based ‘travel stamps’ to create a commemorative record of travel experiences, as part of the firm’s revamped travel app.
The travel experience tokens, which are technically NFTs (ERC 721 tokens), are minted and stored on Coinbase’s Base network, said Colin Marlowe , VP, Emerging Partnerships at Amex Digital Labs.
The travel stamps, which can be collected anytime a traveler uses their card, are not tradable NTF tokens, Marlowe explained, and neither do they function like blockchain-based loyalty points – at least for the time being.
