Too Long; Didn't Read
NFTs (also known as Non-Fungible tokens) could revolutionize e-commerce, online auctions and trade shows. They can be used to track attendance at an event, verify the authenticity of event tickets, or provide a way to collect and redeem rewards earned at the event. Each NFT is unique in its tokenURI. The metadata is where you save details about your NFT including the name, image, description as well as other information. The possibilities for using using these tokens are endless.
