To apply for industrial and commercial registration, you need to use a personal certificate for electronic signature, so you only need to go to the bank that has applied for a bank card and ask if you can apply for a U shield for that card, so that the U shield can also be used, the bank card is safer and the U shield can also be used for signature. Shenzhen is a pilot city for commercial registration reform in China. In order to improve the efficiency of industrial and commercial registration, industrial and commercial registration is handled by the whole network, and the most time-consuming offline paper signature mode in the traditional mode has also been changed to electronic signature. Electronic signature is realized through the U shield of online banking, and the effect is equivalent to electronic identity. The signature port of Shenzhen Administration for Industry and Commerce recognizes digital certificates signed by Ping An Bank, Agricultural Bank, China Bank, China Construction Bank, Industrial and Commercial Bank, China Merchants Bank, China CITIC Bank, Shenzhen Rural Commercial Bank, China Guangfa Bank, Minsheng Bank and Postal Savings Bank. In theory, these banks can use U shields.

After two years of practical experience, we found that some bank digital certificates are difficult to identify, so for the convenience of operation, it is recommended to give priority to the U shield of Ping An Bank and Agricultural Bank. A registered company needs the U shield of the legal representative, supervisors and all shareholders; Usually, the legal representative and the shareholders' meeting overlap, but at least two U shields are needed, because the legal representative and the supervisor cannot be held by the same person. Simply put, take a bank card and open an online banking U shield (with USB interface). After you get the U-Shield, go to the front desk of the bank to find the staff to activate the U-Shield, set the relevant password, and be sure to download the U-Shield certificate to avoid that the U-Shield cannot be used without the certificate. At present, many businesses of Shenzhen company are operated through the whole online process. Therefore, in addition to registering a company, the later "equity change, industrial and commercial change, company cancellation" and other businesses still need U shield.
