Comparison of IC card system and ID card system
IC card is much more secure than ID card. Read the card number in the ID card without any permission, easy to imitate. IC card in the recorded data read and write the corresponding password authentication, and even each area of the card has a different password protection, in order to fully protect data security. IC card in the written data password can be different from the password to read the data, providing a good hierarchical management method to ensure the security of the system.
ID card can not write data, its record content (card number) can only be written by the chip manufacturer once, the developer can only read the card number to use, can not be based on the actual needs of the system to develop a new digital management system.
IC card can not only read a large amount of data by authorized users, but also write a large amount of data by authorized users (such as new card number, user rights, user information, etc.). . IC card records the content can be repeatedly erased.
3. Storage capacity.
ID card only records the card number, IC card (such as Philips) mifare1 card) can record about 1000 characters of content.
4. Offline and network operation
Since there is no content in the ID card, the card holders privileges and system functions are completely dependent on the support of the computer network platform database.
IC card itself records a large amount of user-related content (card number, user information, permissions, consumption balance and other information), and can be run completely off the computer platform to achieve network and offline automatic conversion mode of operation, which can meet the needs of widespread use and less wiring.
5. One card extended application.
ID card can only rely on network software to handle the information of each subsystem, because it has no records and partitions, which greatly increases the dependence on network; if users want to add function points after the ID card system is completed, they need additional wiring, which not only increases the difficulty of engineering construction, but also adds unnecessary investment. Therefore, it is difficult to expand the system using ID card as a system, and it is also difficult to achieve a true one-card.
IC card storage area itself is divided into 16 partitions, each partition has a different password, with multiple sub-system independent management functions, such as the first partition to achieve access control, the second partition to achieve consumption, the third partition to achieve staff attendance, etc.. Fully realize the purpose of one card, can achieve a completely modular design. Even if users want to add functional points, they do not need wiring, they only need to add hardware and software modules, which facilitates the IC card system to be upgraded and expanded at any time in the future, achieving steady upgrade and reducing repeated investment.
For example, a community has already established an ID card card system, but due to the above disadvantages of the ID card system, the system cannot be put into daily use, so it can only be completely invalidated and then use the IC card card system.
6. Maintenance and operation of intelligent systems
For example, when a computer issues new user ID cards, all ID card numbers must be manually downloaded to each ID card reader controller through the network of the ID card system, otherwise the ID card cannot be used as an invalid card; if user privileges need to be changed, the privileged ID card number needs to be entered on each ID card controller.
