It is said that Wang Jianlin once flew 6000 kilometers a day, spanning two countries and three cities, in order to sign a big bill of 50 billion. However, if this list is made today, he may be able to stay at home and save energy to achieve more "small goals". With the update iteration of Internet technology, the operation mode with Internet attributes is gradually becoming the mainstream, and the continuous popularization of electronic signing is a typical example.

Compared with traditional offline signing, electronic signing is obviously more efficient and convenient.

So, what is an electronic signature? Electronic signing, also known as digital signing, refers to the setting and comparison of users' signatures and seals through internet technology, which relieves users' restrictions on space and time on the premise of ensuring safety, and can complete business operations such as contract signing and order confirmation anytime and anywhere without consuming a lot of manpower and material resources.

Ping An Pratt & Whitney, a leading consumer finance service provider in China, launched the unsecured loan product Oxygen Loan, which integrates financial technology means such as big data audit and remote video approval, and can complete the loan through bank-wide operation. Customers don't need to provide any paper materials, not only can they complete the examination and approval through remote video interviews, but they can also sign contracts online, which saves all kinds of troubles in running offline stores.

However, due to the lack of entity sense of traditional offline signing, many users have no real feeling that electronic contracts will take effect immediately. In fact, the legal basis of electronic contract can be found in both contract law and electronic signature law. These laws and regulations not only clarify the equal legal effect of electronic contracts and traditional contracts, but also establish the legal status of electronic contracts from the legislative level.

According to Article 13 of China's Electronic Signature Law, an electronic signature is considered reliable if it meets the following conditions at the same time: (1) When the electronic signature data is used for electronic signature, it belongs exclusively to the electronic signer; (2) When signing, the electronic signature production data is only controlled by the electronic signer; (3) Any changes to the electronic signature after signature can be found; (4) Any changes to the content and form of the data message after signature can be found. "Reliable electronic signature" is not only a technical term, but also a legal term. Article 14 of China's Electronic Signature Law further stipulates: "A reliable electronic signature has the same legal effect as a handwritten signature or seal."

It can be seen that only by using "reliable electronic signature" can electronic contracts have the same legal effect as paper contracts, that is, documentary evidence effect. This is the core of China's electronic signature law, which establishes the legal effect of reliable electronic signatures and lays a good foundation for the legal effect of electronic contracts. Taking Ping An Pratt & Whitney's electronic signature as an example, Ping An Pratt & Whitney's big data analysis, electronic comparison and other technologies provide a guarantee for customers to sign a "reliable electronic signature".

With the continuous development and popularization of Internet technology, electronic signature technology has greatly helped people save time and material costs. When experiencing the convenience brought by the Internet, of course, we should also pay more attention to online operation, recognize the effectiveness of each process, and carefully confirm the responsibilities and obligations that need to be undertaken after each "fingertip click".
