eSign is an online electronic signature service that can facilitate an Aadhaar holder to digitally sign a document. An Aadhaar holder can now sign a document after Biometric/One Time Password authentication thus requiring no paper based application form or documents. Authentication of the signer will be carried out by the e-KYC services of UIDAI and on successful authentication i.e., on receiving the consent from the signer, electronic signature on the document/data will be ascribed by eSign services of NSDL e-Gov. eSign will make the process of digital signature very simple and hence, end-users may adopt it at much faster pace than the traditional DSC. Online service providers can use Open API and easily integrate eSign facility, making the feature of non-repudiation much robust in their existing service.
