<h1>Union Home Ministry requires Aadhaar or alternate ID for smart cards and visitor passes at new secretariat buildings</h1> The Union Home Ministry has mandated Aadhaar authentication for individuals seeking smart cards and visitor passes to access newly constructed central secretariat buildings. The Secretariat Security Organisation, with approval from the Ministry of Electronics and Information Technology and UIDAI, will conduct voluntary Aadhaar-based identity verification. Applicants will be informed of alternative identification options, including PAN Card, Voter ID, Passport, or Departmental ID, and refusal to undergo Aadhaar authentication will not result in denial of access. This measure accompanies the inauguration of a new government office complex designed with advanced security features and centralized access controls to enhance operational efficiency and security for multiple central ministries and departments.
