The difference between smart channel gate IC card and ID card

The difference between IC card and ID card

First, the definition of IC card and ID card

The full name of the IC card is the Integrated Circuit Card, also known as the Smart Card. It is readable and writable, has a large capacity, has an encryption function, reliable data recording, and is more convenient to use, such as the card system and consumer system. PHILIPS Mifare series cards.

The full name of the ID card is the identification card (Identification Card), which is a non-writable induction card with a fixed number, mainly including the EM format of Taiwan SYRIS, the United States HID, TI, MOTOROLA and other types of ID cards.

ID card IC card manufacturer-Jianhe Chengda

Jianhe Chengda Card is a professional inductive IC card and ID card manufacturer. At present, the daily output of various ID cards and IC cards can reach more than 400,000. The products include color printing cards, white cards, key chain cards, wrists With card, thick card, etc., the market covers domestic, Southeast Asia, Europe and America.

Second, why the IC card needs to be initialized (that is, encrypted), but the ID card is not used

1. When the IC card is used, it must first pass the unique two-way key authentication between the IC card and the reading and writing device before it can carry out related work, so that the entire system has extremely high security. Therefore, it must be shipped from the factory. The IC card is initialized (that is, encrypted), the purpose is to generate an unbreakable one-card system key in the IC card after leaving the factory to ensure the safe issuance mechanism of the one-card system.

2. After the IC card is initialized and encrypted, when it is handed over to the user, the customer uses the IC card issuance system to generate each user card's own private key for the system. In this way, it is guaranteed that user cards issued in other user systems cannot be used The use of the system ensures the specificity of the system, thus ensuring the safe use of the system.

3. The ID card is the same as the magnetic card, only the "card number" is used. Except for the card number, the card does not have any security function. The "card number" is open and bare. Therefore, the ID card is an "inductive magnetic card" , It is impossible to talk about the need to initialize or not.

4. Why the initialization process is not left to the user? This is because:

1) If it is initialized by the user, it cannot prevent the internal personnel of the user from doing it because when the user uses the one-card system, if an employee initializes at will with a socially purchased card, he can arbitrarily issue a resident card that can only be used by the resident. Feel free to recharge the card, which will not only cause serious consequences, but also lead to serious loopholes in the use mechanism of the card system.

2) In addition, if the user buys a low-quality factory card and initializes it himself, but cannot use it on the system, it will cause the system to use poor performance or paralysis, which will cause unclear responsibility for the accident.

3) The initialization process is performed by the manufacturer, which is mainly the basic needs of the IC card security key authentication mechanism and the rules of the IC card system integrator. Just like the urban public transportation IC card, these cards are handed over to the bus system before use. The key of the card must be controlled by factory encryption.

4) If the key card for initialization authorization is lost due to the lack of professional management of the user, the user and the manufacturer will not be able to re-use the card. Therefore, the initialization work is performed by the manufacturer to ensure safety.

3. Comparison of IC card system and ID card system

1. Security:

The security of the IC card is much greater than that of the ID card. The card number in the ID card does not have any authority to read, and it is easy to imitate. The reading and writing of the data recorded in the IC card require corresponding password authentication, even each area in the card. There are different password protections 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 tiered management method to ensure system security.

2. Recordability:

The ID card cannot write data, and its record content (card number) can only be written once by the chip manufacturer.The developer can only read the card number and use it.It is impossible to formulate a new number management system according to the actual needs of the system.

The IC card can not only read a large amount of data by authorized users, but also write large amounts of data by authorized users (such as new card numbers, user rights, user information, etc.), and the content recorded by the IC card can be repeatedly erased.

3. Storage capacity:

The ID card only records the card number; the IC card (such as the Philips mifare1 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 function must completely depend 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 away from the computer platform, realize the operation mode of automatic conversion between networking and offline, and can achieve a wide range of use. The need for less wiring.

5. Card extension application:

Because ID cards have no records and no partitions, they can only rely on network software to process the information of each subsystem, which greatly increases the dependence on the network; if the user wants to add function points after the ID card system is completed, additional wiring is required. This not only increases the difficulty of engineering construction, but also increases unnecessary investment. Therefore, it is difficult to expand the system by using ID cards to make the system, and it is difficult to achieve a true one-card.

The IC card storage area itself is divided into 16 partitions, each partition has a different password, and has independent management functions of multiple subsystems, such as partition access control, second partition consumption, third partition employee attendance, etc. The purpose of the card, and can be completely modular design, even if the user wants to increase the function point, there is no need to re-wiring, just add hardware and software modules, which is convenient for the IC card system to be upgraded and expanded at any time in the future, to achieve a smooth upgrade and reduce duplication investment.

For example, a community has established an ID card all-in-one card system, but due to the above-mentioned drawbacks of the ID card system, the system cannot be put into daily use, so the system can only be completely scrapped, and then the IC card all-in-one card system is adopted.

6. Maintenance and operation of intelligent system:

For example, if a computer issues a new user ID card, it is necessary to manually download all ID card numbers to each ID card reader controller through the network of the ID card system, otherwise the ID card is regarded as an invalid card. Cannot be used; if you want to change user permissions, you need to enter the ID card number with permission on each ID card controller.

Another example: after the system is put into use, it is often necessary to add an ID card, then each time a new card is added or the authority of a certain card is modified, the card number must be entered on all controllers available for the card. Increased workload
