NSDL eSign

The Aadhaar card, which was issued by the UIDAI, is now a requirement for Indian citizens. It is now more than simply an identity card; in fact, aadhaar esign can be used for all financial and administrative activities. 

Everyone is required to carry along digital copies of their PAN and Aadhaar card since COVID-19 pushed us to transition to a digital realm. However, aadhaar based esign of your Aadhaar is crucial if you plan to use it online. 

NSDL e-Governance Infrastructure Limited (NSDL e-Gov), a licenced Certifying Authority, has declared that it will support the NSDL esign service, an online electronic signature service. Aadhaar holders may now electronically sign documents using biometric and one-time password authentication. 

What is Aadhaar eSign?

Aadhaar based eSign: Indian citizens may digitally sign documents using their Aadhaar identifying data thanks to the Aadhaar eSign framework. It is a cloud-based electronic signature solution designed to streamline, expedite, and simplify the process of signing official documents.

You need an Aadhaar card and a registered cellphone number that is connected to your Aadhaar card in order to utilise the Aadhaar eSign. Aadhaar authentication and an electronic signature service provider (ESP) are combined into one useful service. According to the Indian Information Technology Act, an ESP is a reputable third-party organisation that has been authorised by the Controller of Certifying Authorities (CCA).

The Aadhaar eSign service and Aadhar eKYC use a same infrastructure. The key distinction is that Aadhaar eSign offers authentication plus other services, whereas eSign NSDL merely offers authentication plus the electronic signature of the Aadhaar holder.

How Does Aadhaar Based eSign Work?

The following stages use Aadhaar data for digital signature in the Aadhaar based eSign method.

Document Upload: The user uploads the document to be signed on the Aadhaar eSign platform as the initial step. The user must provide their Aadhaar information so that the system may retrieve the demographic information from the UIDAI database. To confirm the user’s identity, this information is used.

OTP Authentication: After entering their Aadhaar number, users will be sent an OTP to the registered cellphone number associated with their Aadhaar. A user’s identity is confirmed by the OTP before the signing procedure begins.

Electronic Signature Generation: The Electronic Signature Service Provider (ESP) generates a digital signature on the user’s behalf following successful aadhaar OTP verification. It is essential to recognise that the ESP causes the signature, not the Aadhaar holder, to appear.
Electronic document signing is accomplished using the generated digital signature. The document is given a digital signature by the ESP, which turns it into a signed document with legal standing.

Download/Share: You may download or share the signed document right from the platform. Depending on the ESP or online platform you use, the Aadhaar eSign procedure may vary somewhat. As a result, it is crucial to refer to the detailed instructions offered by the particular ESP or platform.

Is Aadhaar eSign Legal in India?
