Authentication in Progress


World’s Largest Civil ID

World’s Largest Civil ID Project

The world’s largest biometric identity exercise and India’s Unique ID / AADHAAR project is an initiative that would provide identification for each resident across the country and would be used primarily as the basis for efficient delivery of welfare services. It would also act as a tool for effective monitoring of various programs and schemes of the government. The Unique ID / AADHAAR number provided by Unique Identification Authority of India (UIDAI) will serve as a universal proof of identity allowing residents of India to establish their credentials anywhere in the country. 4Gid has made a significant contribution to this World’s largest social inclusion program in different aspects right from the conceptualization stage till deployment and execution.
