# Dynamic Non-Fungible Tokens (dNFTs)
Standard NFTs are immutable. Some use cases would benefit from the capability to update the referenced data object after the initial minting of an NFT. For example, a concert ticket for a postponed event could be updated with an alternate date, or a virtual trading card for an athlete could be periodically updated with current statistics. Dynamic Non-Fungible Tokens (dNFTs) provide the flexibility required for these use cases.
## Creating a dNFT
When minting a new NFT, set the `tfMutable` flag (`0x00000010`) to enable the ability to update the NFT's `URI` field.
## Modifying a dNFT
Use the `NFTokenModify` transaction to update the URI field of a dNFT. Provide the `Account` of the issuer or an authorized minter, the `Owner` of the dNFT (if different than the `Account` address), the `NFTokenID`, and the `URI` to the new object data.
