An NFT can track a physical object, but only as well as the link between the two. A chip, a vault, a legal agreement or a trusted authenticator has to connect the token to the item, and that link, not the blockchain, is what buyers are really trusting.
The core problem: the token does not touch the object
A blockchain can prove who holds a token. It cannot see a sneaker, a watch or a trading card. If the item is lost, swapped or sold separately, the token keeps existing and says nothing about it. Every working phygital design solves this "last mile" in one of a few ways.
Four working models
1. Vaulted custody
The item is stored by a custodian in an insured vault, often after professional grading or authentication. The NFT represents the right to withdraw it. Holders trade the token instantly without shipping anything; whoever redeems gets the item delivered and the token is burned. This is the model behind vaulted trading-card platforms and works best for small, high-value, standardized goods.
Risk: everything depends on the custodian's honesty, solvency and insurance. Buyers should be able to see the custodian's identity, audit reports and terms for what happens if the platform closes.
2. Chip-linked products
A secure NFC chip embedded in the product holds a private key that can sign challenges. Tapping it with a phone proves the physical item is present and genuine, and can be used to claim or verify its NFT. Cheap NFC stickers that only store a URL are easy to clone; use chips with cryptographic signing.
Good for luxury goods, sneakers, art editions and merchandise. The token becomes a certificate of authenticity and ownership history that follows the item through resale.
3. Burn-to-redeem
The NFT is a voucher: burn it to receive a physical item, such as merchandise, a print or a bottle. Often paired with a digital collectible that remains after redemption. Simple, effective, and common for music and fashion drops. Shipping, address collection and taxes are the hard parts, not the contract.
4. Legal-claim tokens
The item is owned by a legal entity or held under a contract, and the token represents that claim. Used for real estate, fine art and other high-value assets. See the real estate NFT guide and art tokenization for those cases.
Design checklist
- Authentication. Who verifies the item before the token is minted, and how is that recorded?
- Custody. Where is the item, who is liable, and what insurance covers it?
- Redemption. How does a holder get the item, what does it cost, and in which countries is shipping possible?
- Token state. After redemption, is the token burned, marked as redeemed in metadata, or kept as a record? Marketplaces must display this clearly so nobody buys a redeemed voucher.
- Exit plan. If the platform shuts down, can holders still claim their items? Write this into the terms.
- Disputes. What happens if the delivered item does not match the description?
Lessons from brand experiments
Many large brands launched phygital collections during 2021 and 2022. Several have since been wound down, including Nike's RTFKT studio, which announced its closure at the end of 2024. The common thread: digital collectibles that depended on ongoing brand investment lost support when strategy changed. Phygital designs where the physical item has value on its own, and the token adds authenticity or convenient resale, aged better than ones where the token was the main product.
Where this fits commercially
Strong fits include vaulted collectibles, luxury authentication, limited-run merchandise, and product passports, where a token or digital record carries a product's origin and repair history. The EU's sustainable products rules are introducing digital product passports for some categories, which creates practical demand for verifiable item records, though they do not require blockchain. For retail-oriented uses, see NFTs in e-commerce. For splitting ownership of expensive items, see fractional NFT marketplaces, keeping in mind that fractions often become securities.
Frequently asked questions
Can an NFT prove a physical item is genuine?
Only together with a secure chip or a trusted authenticator. The NFT records what the authenticator attested; the chip proves the same item is present later.
What happens to the NFT when I redeem the item?
Depends on the design. Most vault models burn the token on withdrawal. Some keep it as a digital collectible marked as redeemed.
Who is responsible if a vaulted item is lost?
The custodian and platform, according to their terms and insurance. Read those terms before buying; the blockchain offers no protection here.
Which chain suits phygital NFTs?
Low-fee chains, such as Polygon PoS or an Ethereum L2, suit most consumer goods. High-value single items sometimes use Ethereum mainnet for its collector base.
