introduces the function comparison of the commonly used IC card and ID card chip:
The security of IC card is much greater than ID card. There is no authority to read the card number in the ID card, which is easy to imitate. The reading and writing of the data recorded in the IC card requires corresponding password authentication. Even each zone in the card has different password protection to fully protect data security. The password for writing data on the IC card and the password for reading out data can be set differently, providing a good hierarchical management method to ensure system security.
The ID card cannot write data, and its recorded content (card number) can only be written once by the chip manufacturer. The developer can only read the card number and use it, and cannot formulate a new number management system according to the actual needs of the system.Not only can authorized users read a large amount of IC card data, but also authorized users can write large amounts of data (such as new card numbers, user rights, user information, etc.). The content recorded in the IC card can be repeatedly erased.
3. Storage capacity
The ID card only records the card number; the IC card can record about 1000 characters.
4. Offline and network operation
Since there is no content in the ID card, the authority of the card holder and the operation of the system functions are completely dependent on the support of the computer network platform database.
The IC card itself has recorded a large amount of user-related content (card number, user information, permissions, consumption balance and other large amounts of information), which can completely run without the computer platform. It can realize the operation mode of automatic conversion between networking and offline, and can meet the needs of large-scale use and less wiring.
5. One card extended application
Because ID cards have no records and no partitions, they can only rely on network software to process the information of each subsystem. This greatly increases the dependence on the network. If, after the ID card system is completed, the user wants to add function points, additional wiring is required. This not only increases the difficulty of project construction, but also increases unnecessary investment. Therefore, it is difficult to expand the system with the ID cards as system, and it is difficult to achieve a true all-in-one card.
The IC card storage area itself is divided into 16 partitions. Each partition has a different password and has independent management functions for multiple subsystems. For example, the first zone realizes access control; the second zone realizes consumption; the third zone realizes employee attendance and so on. It fully realizes the purpose of one card, and can be completely modularized. Even if the user wants to increase the function points, there is no need to re-wiring, just add hardware and software modules. This facilitates the upgrade and expansion of the IC card system at any time in the future, realizes a smooth upgrade, and reduces repeated investment.
IC cards are more and more recognized by users, so IC card systems are more and more accepted by customers. Due to its own defects, the market for ID cards is getting smaller and smaller.
