It is used to provide authentication and proof of identity and intent, enhancing the security of any transaction. The ESF provides a legal and secure method for individuals to provide their signatures and marks online, making it easier to manage documents that require signing. With the ESF, companies can streamline their processes by reducing manual paperwork and increasing the efficiency of operations. Plus, the ESF eliminates the risk of fraud or tampering with documents. Put simply, an Electronic Signature File is a secure yet simple way to manage business transactions.
