What is an Aadhaar Card e-Signature?

With e-Sign Aadhaar, anyone may digitally sign any government document using an online, paperless method. This function is available to anyone with a valid Aadhaar card and an Aadhaar-linked phone number or mail ID. To add a digital signature  to a document, one must also authenticate their Aadhaar signature. They can accomplish this by visiting the UIDAI website, where they must input their Aadhaar number and authenticate themselves with a biometric or One-Time Password (OTP).

Aadhaar Signature Validity

The validity of an Aadhaar signature is essentially an electronic signature used to sign digital documents including agreements, letters, and more. You must now be asking whether it is comparable to a handwritten signature. It is just as valuable as a handwritten signature. There are two versions of an Aadhaar card: the physical card and the electronic version, known as e-Aadhaar. Additionally, two distinct e-Aadhaar versions are available for download: the standard e-Aadhaar and the Masked Aadhaar. Following your online e-Aadhaar download, the digital signature section of your downloaded Aadhaar card in PDF format will have a question mark ('?') that needs to be verified. 

Benefits of Aadhaar e-Signature

  • Convenience:  By removing the need for physical presence to register an Aadhaar card signature, the e-signature feature has made the registration process simple, fast, and real-time for consumers. It also eliminates human mistakes and delays that are an inevitable part of the manual procedure. Hardware tokens, which were an essential component of the procedure, have also been eliminated by the Aadhaar card e-signature.

  • Privacy: The process only involves a limited amount of specified information, preventing service providers from accessing all of it. It is the duty of service providers to protect the confidentiality of the signatory's information.

  • Flexibility: Depending on the device being used by the service provider, there are multiple options to register for an Aadhaar e-signature. The first is biometric verification, which uses fingerprint and iris scanning. Using a mobile device and a one-time password (OTP) is the second method. As part of the verification process, the Aadhaar cardholder in this case receives an OTP on his or her registered contact number. 

How Does Aadhaar e-Signature Work? 

For the end signer, the Aadhaar e-sign procedure is a very straightforward and uncomplicated process. These are the steps it entails: 

  • The signer gets a link to sign by phone, email, or an app on their device (eg. Net banking app, loan app, etc.). After viewing the document, the signer authorises Aadhaar e-Sign. 

  • The signer is then taken to the e-Sign Service Provider Page, where he authenticates OTP, Biometric, and IRIS and enters his Aadhaar number. 

  • The document bears the Aadhaar e-Sign after successful authentication. 

  • The e-signed document is sent to the signer by email or SMS.
