The relationship between dynamic keys and chips

    The general interpretation of dynamic keys is key verification for dynamic passwords, if placed in usSmart card manufacturingAccording to the manufacturer, the password inside a card is dynamic and variable. Generally, the dynamic key can be used in smart card chips, which are variable. This means that after you enter the password once, the password changes the second time. This is the dynamic key.
    So, what is the relationship between a dynamic key and a chip? Because the chip is located in the card, and any function you want to achieve can be set within the chip. If you only want to enter the same password, you can set it in the chip; if you want to make it a dynamic key, you can also set it in the chip. The two are essentially one device and the other functional. This means the chip can perform the functions of a dynamic key, but the device itself can not only perform the functions of a dynamic key. It can also implement other functions, such as locking the password after a few incorrect attempts.
    In short, if you want to implement a certain function inside the chip, you can inform our card manufacturer, and we can set certain functions according to your requirements.
