Digital Identity & QR Verification Engine
ডিজিটাল পরিচয় ও কিউআর যাচাই ইঞ্জিন
Automatic ID issuance with tamper-resistant verification tokens and a public verification page anyone can open from a phone.
The problem
সমস্যা
Printed membership cards could be copied or forged, and there was no way for an employer, institution or citizen to check whether a card was genuine.
The solution
সমাধান
Serial-numbered digital cards issued automatically on verification, each carrying a secret verification token encoded in a QR code that resolves to a server-validated public record showing status, validity and holder details.
Architecture & approach
স্থাপত্য ও পদ্ধতি
Serial generation and verification handled by security-definer database functions so no raw table access is exposed; scan counters, status history and revocation events are logged per card.
Impact
প্রভাব
Forgery becomes detectable by anyone with a phone camera — a direct contribution to institutional trust and member credibility.
Roadmap
রোডম্যাপ
Offline-safe card wallet in the PWA and third-party verification API for employers.
