CFCA is a chartered financial institution in China, which specializes in issuing digital certificates. Electronic signature is a product of Hangzhou Gutian Information Technology Co., Ltd. and an electronic signature product of a third party. Electronic signature is made by using the certificate issued by CFCA organization, because such electronic signature has legal effect.

Now the market is mixed, and many companies are not qualified. Take a photo or hand-draw it as your signature. There is no certificate bound to the CA authority at all. In fact, there is no legal interest in such a signature, and it is useless for you to sign an electronic contract with such an electronic signature. Electronic signature without CA certificate has no legal effect.
