ESign (India)

Aadhaar eSign is an online electronic signature service in India to facilitate an Aadhaar holder to digitally sign a document.[1] The signature service is facilitated by authenticating the Aadhaar holder via the Aadhaar-based e-KYC (electronic Know Your Customer) service.[2]

To eSign a document, one has to have an Aadhaar card and a mobile number registered with Aadhaar. With these two things, an Indian citizen can sign a document remotely without being physically present.

## Procedure

[edit]

The notification[2] issued by Government of India in this regard stipulates the following procedure for the e-authentication using Aadhaar e-KYC services.

## eSign Service Providers

[edit]

Organisations and individuals seeking to obtain the eSigning Service can utilize the services of various service providers. There are empanelled service providers with whom organisations can register as an Application Service Prover after submitting the requisite documents, getting UAT access, building the application around the service and going through an IT Audit by an CERT-IN empanelled auditor.[4]

However, the process of registering as an Application Service Provider is cumbersome, and requires huge investments of time, money and resources in complying with the regulations and building a suitable application. Most organisations prefer using services of plug-n-play gateway providers who take the responsibility of complying with the regulations, hence simplifying the process for the market.
