Comparison of IC card and ID card system

1、Security of IC card is much greater than ID card, the card number in ID card can be read without any authority, which is easy to imitate, and the data recorded in IC card needs corresponding password authentication for reading and writing, even each area in the card has different password protection, which can protect the data safety comprehensively. System security.

Comparison of IC card and ID card system 

2、Recordable 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 out the card number to use, according to the actual needs of the system to develop a new number management system. IC card can not only be read out a large amount of data by authorized users, but also by authorized users to write a large amount of data (such as new card number, user rights, user information, etc.), IC card recorded content can be repeatedly erased.

3, storage capacity ID card only records the card number; while IC card (such as Philips mifare1 card) can record about 1000 characters of content.

4. offline and network operation because the ID card card no content, so the card holders rights, the system function operation to completely rely on the computer network platform database support. IC card itself has recorded a large number of user-related content (card number, user information, permissions, consumption balance and other information), can be completely separated from the computer platform to achieve automatic conversion of networking and offline operation, to achieve a wide range of use, less wiring needs.

5, a card expansion application ID card due to no record, no partition, can only rely on the network software to deal with the subsystem information, which greatly increases the dependence on the network; if the ID card system is completed, the user wants to increase the function point, it is necessary to add another wiring, which not only increases the difficulty of construction, but also increases the unnecessary investment. Therefore, the use of ID card to do the system, it is difficult to expand the system, it is difficult to achieve a real card. The IC card storage area itself is divided into 16 partitions, each partition has a different password, with multiple subsystems 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 a card, and can do completely modular design, even if the user wants to increase the function point, there is no need for wiring, only to increase the hardware and software modules, which facilitates the IC card system to upgrade and expand at any time later, to achieve a smooth upgrade, reduce repeated investment. For example, a district had established an ID card card system, but due to the above-mentioned drawbacks of the ID card system, the system can not be put into daily use, so the system can only be completely abolished, and then changed to use the IC card card system.

6, intelligent system maintenance and operation, such as the computer issued a new user ID card, it must be through the ID card system network, with the manual way to download all ID card number one by one to each ID card reader controller, otherwise the ID card is invalid as a card and can not be used; if you want to change the user rights, it is necessary to enter the ID card number on each ID card controller has the right. Another example is that after the system is put into use often to add ID cards, each new card or modify the permission of a card, it is necessary to enter the card number on all controllers available on the card, which increases the workload
