Overview
Students can borrow physical or digital assets (books, lab equipment, lockers) by presenting a Student ID Verifiable Credential at the point of access.
Why it matters
Traditional borrowing requires kiosks, staff intervention, or physical ID cards. A wallet-based credential streamlines the experience while keeping identity assurance consistent.
Ecosystem roles
- Issuer: The education institution issuing student identity credentials.
- Holder: The student storing the credential in a wallet.
- Verifier: Library or asset management system validating the credential at checkout.
Implementation notes
QR codes or NFC prompts can initiate presentation. The verifier records the transaction in the asset management system without storing unnecessary personal data.
