Compatible Devices & Platforms

Operating System & Platform Support

Android

Android's Credential Manager API (Android 14+) provides standardized support for digital credentials, including mDLs and other VCs. Many third-party wallets are available on the Play Store.

Support can vary by device manufacturer and OS version.

iOS (Apple Wallet)

Apple Wallet supports digital IDs like driver's licenses and state IDs in participating US states. Support for broader W3C VCs is emerging via third-party wallet apps.

Requires iOS 15+ for basic features, newer versions for expanded ID support.

Web Browsers

Browser extensions can act as wallets. Web-based verification flows (e.g., using OpenID4VP) allow interaction with desktop or mobile wallets. APIs like WebAuthn are also relevant for binding credentials to devices.

User experience can vary based on wallet extension and browser.

Windows

Support for digital credentials on Windows is evolving. Microsoft Entra Verified ID can be managed. Some applications might integrate with external wallets or hardware tokens.

Wallet Availability

A variety of digital wallet applications are available, each with different features and supported credential types. When choosing a wallet, consider:

• Standards Support: Does it support W3C VCs, SD-JWTs, mdocs (ISO 18013-5)?
• Security Features: How are private keys stored? Does it support biometric protection? Secure Enclave/Hardware-backed storage?
• User Experience: Is it easy to import, manage, and present credentials?
• Portability & Backup: Can you easily backup and restore your wallet or move credentials between devices?
• Open Source / Vendor Lock-in: Is the wallet based on open standards and are you in control of your data?

You can find wallets on the Google Play Store, Apple App Store, or directly from providers. Some are focused on specific ecosystems (e.g., government-issued IDs), while others are more general purpose.

Hardware Considerations

For high-assurance credentials, especially mobile identity documents (mdocs), hardware security features are crucial:

• Secure Elements (SE) / Trusted Execution Environments (TEE): These provide hardware-level protection for cryptographic keys and sensitive data, making it extremely difficult to extract or tamper with them.
• NFC (Near Field Communication) & BLE (Bluetooth Low Energy): Essential for offline data transfer (e.g., presenting an mDL to a reader device). ISO 18013-5 defines protocols for these interactions.
