"NFT" stands for "Non-fungible token", which means that it's a unique, digital item with Blockchain-managed ownership that users can buy, own, and trade. Some NFT's fundamental function is to be digital art.

Think of it as a unique piece of art that can also work as a "Members-Only" card. Xeno B's works like this.
