American Express startet Travel Stempel NFTs auf der Basis

tldr; American Express has launched travel stamp NFTs for US cardholders, allowing them to collect digital stamps for each country visited. These stamps, minted as ERC-721 tokens on Base, are viewable in the Amex mobile app and commemorate global travel. A crypto wallet is created for users behind the scenes, but they won’t directly interact with the blockchain or trade stamps. The initiative aims to enhance the travel experience in a digital age, with stamps symbolizing permanence akin to physical passport stamps.

Yeah the lufthansa group has a similar app called Uptrip where you can collect nfts per boarding pass and export them to polygon

Base could blow up massively once they launch their own token.
