The primary purpose of Raj eSign is to provide a secure and authorized electronic signature for hassle-free digital signing of electronic self-attestation and e-verification. It is a service that allows applications to replace manual paper-based signatures by integrating an API which allows an Aadhaar holder to sign electronically. The government of Rajasthan has initiated Raj eSign to bring ease in the complex processes that include lengthy paperwork.

The Electronic Signatures in Global and National Commerce Act (E-Sign Act) is a U.S. federal law that specifies that electronic records and signatures are legally valid for interstate and foreign commerce transactions. The E-Sign Act allows the use of electronic records to satisfy any statute, regulation, or rule of law requiring that such information be provided in writing, if the consumer has affirmatively consented to such use and has not withdrawn such consent. The act validates electronic records and signatures for interstate and foreign commerce transactions, which saves companies that use e-signatures a significant amount of money by reducing mailing and handling costs for hard-copy contracts and similar documents.
