Identity protocols can support equipment rental shops by issuing verifiable credentials (VCs) to customers, proving eligibility (e.g., age, license validity) via decentralized identifiers (DIDs). Smart contracts track rentals, linking VCs to IoT-enabled locks for secure equipment access. Zero-knowledge proofs verify credentials without exposing sensitive data, while blockchain ledgers maintain transparent usage histories. Deposit VCs automate refunds upon safe return, reducing disputes and administrative overhead.
