AMERICAN EXPRESS INTRODUCES BLOCKCHAIN-BASED ‘TRAVEL STAMPS'

Summary from the TLDR Crypto newsletter

American Express' "travel stamps," part of its revamped travel app, allow customers to create commemorative records of travel experiences through ERC-721 tokens minted and stored on Coinbase's Base network. The digital passport stamps, which can be collected whenever travelers use their Amex card, are technically NFTs, but are deliberately not branded as such, as the company wanted to speak to the travel experience naturally rather than emphasize the blockchain technology. The stamps are not tradable tokens and don't function as blockchain-based loyalty points currently. They could create interesting partnership angles over time as identifiers and representations of travel history.
