What is Citizen Services?
Citizen Services technology encompasses the digital platforms governments build to serve citizens — identity verification (Aadhaar), document storage (DigiLocker), benefit delivery (DBT), public grievance systems, and service delivery portals. India's Digital Public Infrastructure (DPI) — Aadhaar (1.4B enrollments), UPI (10B+ monthly transactions), and DigiLocker — is recognized globally as a model for population-scale technology. Citizen services platforms handle everything from birth certificates and driving licenses to pension disbursement and disaster relief. Understanding this domain teaches you identity systems, population-scale architecture, and inclusive technology design.
