eid viewer app

eid viewer app is a tool to parse and display essential data stored on electronic identity documents (eIDs). It focuses on data extraction, format normalization, and lightweight validation to support developers, QA engineers, and security teams during integration, compliance checks, and secure test environments. The tool accepts standardized data payloads or simulated card responses and presents a consistent data model, enabling reproducible verification without requiring live readers. It emphasizes privacy by exposing only permitted fields and by offering optional redaction for sensitive values during testing.
Conceptually, the tool abstracts the underlying card interfaces, decodes data groups, and exposes a uniform view of core attributes such as holder name, document number, expiry date, issuing authority, and credential type. It supports multiple eID schemes (national IDs, residency cards, ePassports where applicable) and can simulate verification steps by applying domain rules like expiry validity, certificate status, and signature freshness. Data normalization converts varied formats into a stable schema, enabling downstream processes to compare results across devices and jurisdictions.
Core differentiators include jurisdiction-agnostic data mapping, offline operation on supplied samples, cryptographic validation checks, and export-ready results for audits and compliance reporting. The tool targets API developers, QA engineers, security auditors, and identity-management teams who need reproducible verification results and clear data lineage. It also supports extensible plug-ins for new document types and configurable validation rules, ensuring the same tool remains useful as issuance standards evolve. Batch processing and sample export facilitate automated testing pipelines.
Use cases include integration testing of identity workflows within enterprise systems, validation of data extraction in identity-as-a-service pipelines, privacy-preserving verification in development environments, and documentation of eID data schemas for audit readiness. It handles invalid structures, missing optional fields, and external data unavailability by providing clear error signals and fallback behaviors. The tool supports logging of actions for traceability, and can be configured to export results in JSON or CSV for integration with existing governance platforms.
