About

MATTR GO Verify

Features
Read full description

The MATTR GO Verifier provides a quick and easy way to perform secure, in-person verification of Compact and Mobile credential profiles. Designed for seamless interactions, the app allows verifiers to scan a QR code presented by a credential holder and confirm the authenticity and integrity of their credentials in real-time. Using privacy-preserving techniques, the app ensures that no data is stored, and credential information is only visible for a limited time. Built using the MATTR Pi Verifier SDKs, this app demonstrates the full range of MATTR in-person verification capabilities. Key Features: - Mobile Credentials Support: Request and verify mDLs (ISO 18013-5) and mdocs (ISO/IEC TS 23220-4) via a secure Bluetooth connection with the holder's digital wallet. - Scan and Verify: Instantly verify Compact credentials by scanning a QR code from the credential holder. - Real-Time Results: View verification outcomes along with relevant credential information. Functionality - Pre-configured setup: Start quickly with ready-made configurations including trusted issuers, namespaces, and certificates. - Trusted issuers: Ensure credentials are issued by trusted entities, as defined in the app’s trusted issuer list. - Customizable display: Tailor the result screen to highlight either verification status or detailed credential information. - Auto-hide results: Configure the app to automatically hide verification results after a set period for enhanced privacy. - Optimized scanning: Use flashlight and reverse camera functions to improve scanning in low-light or other challenging environments. The MATTR GO Verifier ensures secure, efficient, and reliable verification of credentials, making in-person interactions fast, trustworthy, and user-friendly.
