Difference between ID card and IC card

1, IC card and ID card definition
　　IC card universal IC card (Integrated Circuit Card), also known as a smart card (Smart Card). Can read and write large capacity, there is encryption, data recording, reliable, more convenient, such as card systems, consumer systems, is currently mainly PHILIPS's Mifare series cards.
　　ID card universal identification card (Identification Card), is a proximity card can not be written, containing a fixed number, mainly in Taiwan SYRIS the EM format, the U.S. HID, TI, MOTOROLA and other types of ID cards.
2, why do IC card is initialized
　　IC card, when used, must be first through the IC card and read-write devices specific to the two-way key authentication before they can carry out relevant work, so that the whole system has a very high security. Therefore, it is necessary for the factory IC card is initialized (ie encryption), aimed at the factory after the IC card can not be generated to break the key-card system to ensure system security card payment mechanism.
　　IC card initialization encrypted, to the user, the client through the IC card issuance systems, in turn generate their own system, each user cards dedicated key. In this way, ensure the user's system in the other cards issued by the user can not use the system to ensure the specificity of the system, thus ensuring the safety of the system to use the mechanisms.
　　ID cards and magnetic cards, like, are merely using the "card number" and it apart from the card outside the card number, without any security features, its "card number" is open and exposed. So the ID card is the "magnetic induction", they did not mention 　　　　　the need or do not need to initialize the problem.
　　Why do not the initialization process by the users themselves to do it, as four reasons:
① If the user is initialized, it can not prevent a user-house staff cheating. Because the user using the card system, a worker with the community bought a card at random initialization can be freely released into the household to use the household card, or even free to Recharge Your Card consumption, which will not only cause serious cheating consequences, will also lead to the use of card system, safety is a serious loophole in the mechanism.
② In addition, if customers buy their own shoddy factory card initialization, but the system can not be used, then the system will use the performance of poor or paralysis, which will result in unclear responsibility for the accident.
③ initialization process in the factory implementation, mainly IC card security key authentication mechanism of the basic needs, but also IC card system integrator of the guild regulations. As urban public transportation IC card, these cards to the public transport system before use, each card should be factory key encryption controls.
④ If the result of a lack of professional management of the user in case lost license to use the key card is initialized, users and manufacturers will be unable to fill with the card. Therefore, the initialization done by the manufacturers, only security.
3, IC card system with the ID card system comparison
① Security:
　　IC card security is far greater than ID cards. ID card of the card number without any permission to read, easy to imitate. Record data within the IC card read, write the corresponding password authentication is required, or even cards in each district have a different password-protected, comprehensive protection for data security, IC card to write data, passwords and the password can read data Set different level management provides a good way to ensure system security.
② Recording of:
　　ID card is not write data, the contents of its records (card number) only by chip-making plant write-once, the developer should be used only to read out the card number can not be according to the actual needs of the system to develop new number management system.
　　IC Card not only by authorized users to read large amounts of data, but also by an authorized user to write large amounts of data (such as a new card number, user permissions, user information, etc.), IC card erase the recorded content can be repeated.
③ Storage Capacity:
　　ID card is only recorded card number; while IC card (such as Philips S50/S70 mifare1 card) can record the contents of about 1,000 characters.
④ offline and networking run:
　　No content within Kaka as ID, so the card holder's permission, the system functions to be performed to be completely dependent on computer network platform database support.
　　The IC card itself has recorded a large number of users to relevant content (card number, user information, access, consumption, balance of large amounts of information, etc.), can run from the computer platform, networked and offline automatic conversion operation modes, can achieve large-scale use of , less wiring needs.
⑤ Card Extended Application:
　　ID cards due to no records, no partition, to rely on network software to handle the various subsystems of the information, which greatly increased dependence on the network; if the ID card system is complete, the user wishes to increase the function point, you will need additional wiring, This not only increased the difficulty of construction, but also an unnecessary increase in investment. Therefore, the use of ID card to do the system, it is difficult for system expansion, 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, the independent management functions with multiple subsystems, such as the first district to achieve access control, and the second partition to achieve consumer, employee attendance, and so to achieve third partition. The full realization of the purpose of card and can be completely modular design, the user even if the points to increase the functionality, but also no need for cabling, simply by adding hardware and software modules, which facilitate the IC card system update at any time after the expansion to achieve a smooth upgrade reduce duplication of investment.
　　For example: A district has established the ID card card systems, ID card system because of the above-mentioned drawbacks, the system can not be put into everyday use, so the system can only be completely nullified, changed after the use of IC card card system.
