U shield is a tool for electronic signature and digital authentication of online banking. It has a built-in micro smart card processor, and uses 1024-bit asymmetric key algorithm to encrypt, decrypt and digitally sign online data to ensure the confidentiality, authenticity, integrity and non-repudiation of online transactions.
As a kind of digital electronic signature, U shield replaces shareholders to sign in the window of State Administration of Markets, which greatly reduces the pressure of the industrial and commercial window and the time cost for investors to come back to the window of State Administration of Markets to verify their identity, and also meets the rigid demand of current e-commerce and e-government. The supported banks are ICBC, CCB, BOC, ABC and Ping An, and companies can be registered.
