Decentralized identity can improve aquarium visits by enabling self-sovereign memberships stored in digital wallets. Visitors present verifiable credentials (VCs) via QR codes or NFC for contactless entry, reducing wait times. Aquariums can issue dynamic tickets linked to user preferences (e.g., disabled access), personalizing experiences. Blockchain-based loyalty programs reward frequent visitors with redeemable VCs. This enhances privacy, streamlines operations, and fosters repeat engagement through secure, user-centric data management.
