With years of develop and manufacturing experience on network security and related tokens and smart display cards, HierStar offers press button dynamic CVV code card, CVV code is dynamic password, which use LCD displayer to solve the problem of preventing middle-man obtaining personal information and fraulding on the offline tansactions.

The dynamic password authentication system developed by HierStar supports National SM3 algorithm. System is compatible with the CVV code certification, which can effectively prevent middle-man attacking, and secure offline transactions.Based on dynamic authentication, the system receive users’ inputting authentication information (such as account number, CVV code) from application interface or application system, and then read the corresponding information fromo database, and perform authentication, finally send back authentication results to the authentication proxy or application system, and record user’s authentication information. Authentication proxy allows users integrate dynamic authentication service through simple configuration, without secondary development. System SDK provides authentication function in the form of interface. User can integrate authentication service into own application system with these interfaces, which can realize seamless integration with application system.
