You can choose an electronic contract or a paper contract according to your actual situation, not who will replace who.
For example, if you sign in different places, you can choose electronic signature to reduce costs and increase efficiency for enterprises.
The definition of electronic signature in Electronic Signature Law is: "It is contained in a data message in electronic form, accompanied by data for identifying the identity of the signer and indicating that the signer approves its content". In other words, legal and compliant electronic signatures have the same legal effect as handwritten signatures.
