The Taiwan Digital Identity Wallet (TW DIW) is an innovative technology initiative led by the Ministry of Digital Affairs, designed to redefine how we manage identity, authorize data, and access public and private services in the digital age. It’s more than just a way to carry fewer cards—it’s a new framework for living digitally with simplicity, security, and self-sovereignty.
TW DIW is built on global standards such as Verifiable Credentials (VC) and Decentralized Identifiers (DID), and integrates privacy-enhancing technologies like decentralized storage, biometric authentication, and selective disclosure. These features empower users to take full control of their personal data while enabling fast, secure identity verification across diverse real-world scenarios.
Your Gateway to Digital Living
Have you ever been unable to complete a task because you forgot your ID? Or felt uncomfortable revealing too much personal information just to pick up a package? TW DIW was created to solve these everyday challenges.
With the TW DIW mobile app, you can digitally manage credentials like student IDs, driver’s licenses, technician certificates, and membership cards—all in one place. When needed, you can authorize their use without presenting physical documents or going through tedious procedures. It’s truly “one device, seamless access.”
TW DIW supports QR code scanning and NFC contactless verification, and incorporates on-device biometric authentication (such as fingerprint or facial recognition) to ensure your data never leaves your phone. Whether you’re borrowing a book on campus, applying for government services, picking up a delivery, or checking into an event, TW DIW lets you verify and authorize with just a tap.
Data Ownership, Privacy Without Compromise
At the heart of TW DIW is the principle: “Your data, your control.” Users can choose what information to share and with whom. For example, to prove you’re over 18, you can disclose only your birthdate—without revealing your name, address, or other sensitive details. This selective disclosure, powered by zero-knowledge proof technology, enhances both privacy and trust.
All credentials are stored locally on your device, while trust registries are recorded on public blockchains—eliminating the risks of centralized databases. Even offline, your credentials remain verifiable, ensuring uninterrupted service and uncompromised data protection.
One App, Infinite Possibilities
TW DIW is your all-in-one gateway to digital services. Whether logging into government platforms, applying for subsidies, attending events, or verifying your identity across borders, TW DIW streamlines the process. It’s not just a tool—it’s a new way of life, freeing up your time for what truly matters.
