• Secure Storage: Stores verified identity credentials (e.g., ID cards, driver’s licenses, professional certificates, health records) in a safe, encrypted environment.
• Identity Verification: Allows individuals to prove their identity to service providers without repeatedly sharing full personal details.
• Selective Disclosure: Lets users share only specific identity attributes (e.g., age verification without showing full birth date) to preserve privacy.
• Cross-Border Interoperability: Enables identity verification across countries in compliance with regulations like eIDAS 2.0.
• Credential Issuance and Management: Supports receiving, storing, and updating digital credentials from trusted issuers.
• Integration with Services: Works with public services, banking, healthcare, e-commerce, and more for seamless authentication and transactions.

Difference Between Digital ID Wallets vs. Traditional ID Systems

Digital Identity Wallets mark a major evolution from physical IDs and legacy KYC systems. While traditional methods rely on manual verification and static documents, wallets introduce automation, security, and cross-border usability.

How Digital Identity Wallet Works for Governments & Banks?

Digital identity wallets operate similarly for governments and banks, offering a secure, efficient way to issue, manage, and verify identities while reducing reliance on paper-based systems. Here’s a step-by-step process.

1. Identity Issuance

The process begins when a government authority or a bank issues a verified digital identity to a citizen or customer. This digital identity is stored within the wallet, replacing the need for physical documents such as ID cards, passports, or bank KYC forms.

2. Secure Storage

The digital identity wallet uses advanced encryption to protect personal data. The information is stored on the user’s device, ensuring that the individual remains in full control of when and how the data is shared. This decentralized approach minimizes the risks associated with centralized databases.

3. Consent-Based Data Sharing

Whenever verification is required such as opening a bank account, applying for a government service, or passing a compliance check, the user can grant consent to share only the necessary data. For example, instead of sharing a full ID, the wallet can verify just the age or nationality.

4. Real-Time Verification

Governments and banks can instantly verify the authenticity of shared credentials using trusted digital signatures. This speeds up processes like KYC checks, license applications, or benefit disbursements, reducing manual paperwork and delays.

5. Ongoing Updates & Management

The wallet is not static. It can be updated with new credentials, such as a new driver’s license, voter ID, or updated financial information. This ensures that the user’s digital identity remains current and valid without repeated in-person visits.

6. Enhanced Trust & Efficiency

By streamlining verification and minimizing data exposure, digital identity wallets build greater trust between users, governments, and banks. They reduce fraud risks, enhance compliance, and deliver faster, more user-friendly services.
