# ZKPassport > Verify your identity without giving up your privacy ZKPassport enables privacy-preserving identity verification using passports and ID cards through zero-knowledge proofs. ZKPassport enables privacy-preserving identity verification using government-issued passports and ID cards. Users can prove specific identity attributes like age or nationality without revealing personal information. The platform uses zero-knowledge proofs to verify document authenticity while maintaining privacy. - Type: Company - Sector: Privacy & Confidentiality - Status: Active - Profile: https://thegrid.id/profiles/zkpassport ## Products - [ZKPassport SDK](https://thegrid.id/profiles/zkpassport): ZKPassport SDK implements privacy-preserving identity verification through zero-knowledge proofs, enabling developers to request specific identity attributes from passports and ID cards without exposing unnecessary personal information. The system processes identity documents locally on devices and generates cryptographic proofs for selective disclosure of attributes such as age, nationality, or name. (Developer Tooling, Live, Main Product) - [ZKPassport Mobile App](https://thegrid.id/profiles/zkpassport): ZKPassport Mobile App implements NFC-based identity document scanning and local zero-knowledge proof generation, enabling users to verify identity attributes from passports, ID cards, and residence permits without revealing personal data. The application processes all identity information locally on the device to ensure complete privacy. (Decentralised Identity, Live) - [Registry Explorer](https://thegrid.id/profiles/zkpassport): Registry Explorer implements a comprehensive interface for exploring certificates and historical registry data, providing users with tools to search certificates, verify their authenticity, and browse historical merkle roots for both certificate and circuit registries with their validity periods and counts.
