When you think "what is eSign?" consider it as the digital equivalent of your handwritten signature. Unlike the traditional method of signing physical documents, eSign, allows you to digitally sign documents, making it a key facilitator of our increasingly paperless world. This technology offers a more convenient, efficient, and eco-friendly alternative to the old-school process of signing, scanning, or mailing documents.

eSignatures, like the Aadhaar eSign, come in various forms, ranging from simple ones like typed names or scanned images of hand-written signatures to more complex types like cryptographic signatures. Aadhaar-based eSign, for instance, is a type of eSignature that employs cryptographic methods for verification, ensuring the signer's identity and the document's integrity.

In essence, "What is eSign?" is a question with an empowering answer. It's a tool that harnesses the power of technology to make our lives easier, faster, and more secure. Aadhaar eSign, as a prime example, is revolutionizing how we sign documents in India. Whether you're signing a contract, approving a transaction, or authenticating a document, eSignatures has got you covered.

Benefits of Aadhaar eSign

Now that you know "what is eSign" and "what is Aadhaar eSign", let's consider why you should use it. Aadhaar eSign provides a host of advantages:

1. Convenience: With Aadhaar eSign, you can sign documents from anywhere and anytime. All you need is an internet connection.

2. Security: Aadhaar eSign is highly secure. It uses two-factor authentication, ensuring that only you can sign your documents

3. Legally Binding: Aadhaar eSign is legally recognized in India. This means that an Aadhaar-based eSign holds the same legal status as a handwritten signature

4. Time-saving: Aadhaar eSign saves you time. No more printing, signing, and scanning documents!

How to Use Aadhaar eSign

The process of using Aadhaar eSign is quite straightforward and user-friendly, and it's designed with the signer's convenience and security in mind. Here's how it works:

  • When a user sends a document for Aadhaar eSign, the signer will receive a notification via email. This email will contain a link that directs the signer to the Aadhaar eSign platform. To proceed with the eSign process, you need the signer's Aadhaar number and registered mobile number. Only the signer knows this information, making sure the process is safe and the signer's identity is kept private.
  • Once the signer enters their UID number, an OTP (One-Time Password) is sent to the registered mobile number. The signer needs to input this OTP into the Aadhaar eSign platform to verify their identity. This two-step authentication process ensures that only the intended signer can eSign the document.
  • After successful verification, the signer can proceed to eSign the document. The document is returned to the user, now carrying the secure and legally recognized Aadhaar eSign.

Which documents can you sign with Aadhaar eSign?

Aadhaar eSign has a broad scope of use, making it an incredibly versatile tool for Indian citizens. With Aadhaar eSign, you can digitally sign a variety of documents, covering an expansive range of needs. This includes legal contracts, which might be anything from business agreements to employment contracts.

Additionally, you can use it for financial documents such as loan agreements, demonstrating its usefulness in banking and finance scenarios. Rental agreements, service contracts, and many other types of agreements can also be signed using Aadhaar eSign.

Yet, it's crucial to remember that Aadhaar eSign does have its limitations. It's not suitable for every legal document. For instance, documents that mandate a witness signature, like certain types of deeds, cannot be signed with Aadhaar eSign.

Similarly, wills or testamentary documents, which often require specific formalities like the presence of a witness, cannot be signed using Aadhaar eSign. So, while Aadhaar eSign is a powerful tool, it's important to understand its scope and limitations to effectively and legally utilize it.

Comparing Aadhaar-based eSign with Email-based eSign

Aadhaar based eSign

  1. Government Initiative: Aadhaar eSign is a service endorsed by the Indian government, lending it a high degree of credibility.
  2. Identity Verification: It uses the unique 12-digit Aadhaar number for identity verification, ensuring that the signature is linked directly to the signer's identity.
  3. Security: Aadhaar eSign offers high security as it uses two-factor authentication - biometric or OTP (one-time-password).
  4. Legal Standing: As it is backed by the Indian government, Aadhaar eSign is legally recognized and enforceable under the Indian IT Act, 2000, providing a strong legal framework.

Email based eSign

  1. Email Authentication: Email-based eSign involves creating a digital signature using email authentication, which is less secure compared to Aadhaar eSign.
  2. Convenience: While it offers convenience and is quick to use, it lacks the robust security that Aadhaar eSign offers. No Government-Verified ID: Email-based eSign isn't linked to any government-verified ID, making it less reliable in terms of identity verification.
  3. Legal Recognition: The legal recognition and enforcement of email-based eSignatures can vary greatly depending on the specific situation and jurisdiction.

Global Recognition of Aadhaar-based eSign

Aadhaar eSign is gaining international attention because of its potential to streamline digital transactions. This innovative approach is recognized by many countries for its efficiency and security, and its model is being studied for potential adoption in other developing nations.

Internationally, Aadhaar eSign aligns with eIDAS, the European regulation for electronic identification and trust services, making it globally compliant. Moreover, it's appreciated by global institutions like the World Bank for its potential in promoting digital inclusion.

Aadhaar eSign is known worldwide as a successful, secure, and user-friendly digital signature solution. It demonstrates India's digital capabilities on a global level.
