The Aadhaar eSign, introduced by the Unique Identification Authority of India (UIDAI), offers a paperless solution that allows individuals to add a secure digital signature to their Aadhaar card or other documents. With this feature, users can sign any official document from anywhere, as long as they have access to their Aadhaar-linked mobile number or email ID. This article will explore how Aadhaar eSign works, methods to validate the Aadhaar signature, and its significance in the modern world.
