" summary

Shows how a delivery app replaces photo IDs with a cryptographically signed verifiable credential encoded as a JSON Web Token using the web5 SDK, where the mobile driver's‑license issuer signs a claim like over 21=true tied to a holder's decentralized identifier. Verifiers (vendor and delivery app) check signature, expiry and a presentation definition; examples include MIT diplomas, KYC, Aruba passport pilots, Apple/Google wallets (about 13–14 states involved), with the main hurdle being standardization and interoperability.
