What Is The Difference Between IC Card And ID Card？

 

 

The ID card only records the card number, and there is no authority to read the card number in the card, so it is easy to imitate. The ID card cannot write data, and its recorded content (card number) can only be written by the chip manufacturer at one time, and the developer can only read the card number for further processing. It is impossible to formulate a new number management system according to the actual needs of the system.

 

The reading and writing of data recorded in the IC card requires corresponding password authentication, and even each area in the card has different password protection to fully protect data security. The password for writing data in the IC card and the password for reading data can be set For different reasons, it provides a good hierarchical management method to ensure system security. IC cards can not only read a large amount of data by authorized users, but also allow authorized users to write large amounts of data (such as new card numbers, user permissions, user information, etc.), IC cards The content recorded in the card can be repeatedly erased and written. The security of the IC card is much greater than that of the ID card.
