How Ethereum is powering physical access control (like door keys, smart locks, and car access) with transparency and security built into the blockchain. • Ethereum-based access control systems work by issuing NFTs as digital keys. If your wallet holds the right token, smart-lock hardware recognizes it and grants access no traditional keys or keycards required. This model enables programmable, revocable, and transferable permissions • Protocols like @UnlockProtocol offer NFT membership tokens that act as access credentials. These tokens can be configured with time limits or renewable durations ideal for use cases like events, hotels, gyms, or co-working • Early pioneers such as @slockitproject it imagined tying Ethereum smart contracts to IoT devices where your wallet’s permissions could unlock physical spaces or assets.

More recently, Ethereum developers have introduced EIP‑5791 (Physical Backed Tokens) a standard where real-world objects embed secure chips that verify token ownership.
