At present, my country's Contract Law has listed data messages, including electronic data exchange and email, as one of the written forms of contracts, thus laying the foundation for the legalization of electronic signatures. However, our country's current laws have not determined that electronic signatures have the same legal status as handwritten signatures. Some legal provisions still strictly stipulate that written signatures must be used. For example, our country's current "Negotiable Instruments Law" does not recognize illegal signatures that have been authenticated by electronic signatures. Paper-based electronic bill payment and settlement methods do not legalize electronic signatures, are not conducive to Internet transactions, and are contrary to international practice.
