What fields are electronic signatures used in and what are the differences from paper signatures?

I. Scope of application of electronic signature:

In fact, electronic signature has been applied in many fields, such as HR, B2B, online business travel, O2O, P2P, leasing industry, third-party payment and so on. ?

Second, electronic signatures are different from traditional signatures:

Electronic signature is mainly applied to electronic contracts by means of electronic technology. In today's increasingly popular e-commerce, contracts or documents are often expressed and transmitted electronically.

Traditional handwritten signatures can't confirm the identities of both parties to a transaction, so it is necessary to identify the real identities of both parties in electronic documents by technical means to ensure the security, authenticity and non-repudiation of the transaction. This electronic technique is called electronic signature.
