1.Definition of IC card and ID card

IC card, also known as smart card, can be read and written, large capacity, encryption function, reliable data record, more convenient to use, such as consumption system is commonly used IC card.  PHILPS 'Miifare series cards are the main IC cards.

ID card full name identification card, is a can not write induction card, with a fixed number, mainly Taiwan SYRIS EM format, HID card, TI, MOTOROLA and other ID card.

2.The working principle

IC cards do initialization (that is, encryption) work, but ID cards do not.  IC card in use, must first through the IC card and read and write equipment unique two-way key authentication, in order to carry out related work, so that the whole system has a high security.

Therefore, it is necessary to initialize (encrypt) the IC before delivery to generate an uncrackable system key in the IC card after delivery to ensure the secure provisioning mechanism of the system.  After the IC card initialization encryption, to the user to use, the customer through the IC card issuance system, and the user card will generate their own system private key.  In this way, it ensures that the user card issued in other user systems can not be used in the system, to ensure the specificity of the system, so as to ensure the safe use mechanism of the system.

Like magnetic cards, ID cards only use the "card number".  There is no security function except the card number in the card, and its "card number" is open and naked.  Therefore, ID card is "induction magnetic card", also the main need or no need to initialize the problem.

Why not let the user do the initialization?  

This is because:

A. If it is initialized by the user itself, it cannot prevent cheating by internal users.  When using the one-card system, if an employee initializes the card at will with the card purchased from the society, the card can be randomly issued as a household card, or even can recharge the card at will.  This will not only cause serious cheating consequences, but also lead to serious loopholes in the security mechanism of the one-card system.

b. In addition, if the user buys the inferior factory card and initializes it by himself and cannot use it in the system, the system performance will be poor or paralyzed, which will lead to unclear liability for the accident.

c. The initialization process is carried out in the manufacturer, which is mainly the basic requirement of the IC card security key authentication mechanism, and also the industry regulation of the IC card system integrator.  Just like urban public transport IC cards, the keys of each card are encrypted before they are handed over to the bus system.

d. If the key card used for initial authorization is lost due to the user's lack of professional management, the user and the manufacturer will not be able to replace the card.  Therefore, the initialization work is done by the manufacturer, so that there is security.

3.Comparison between IC card system and ID card system

a.security: the security of IC card is far greater than that of ID card.  ID card number read without any permission, easy imitation.  The reading and writing of the recorded data in the IC card need the corresponding password authentication, and even each area of the card has different password protection, comprehensive protection of data security, IC card write data password and read data password can be set to be different, providing a good hierarchical management mode, to ensure system security.

b. Recordability: The ID card cannot write data, and its record content (card number) can only be written by the manufacturer at one time, and the developer can only read the card number for use.  It is impossible to formulate a new number management system according to the actual needs of the system.  IC card can not only be read by authorized users, but also by authorized users to write a large number of data (such as the new card number, the user's authority, user information, etc.), IC card recorded content can be repeatedly erased.

C.storage capacity: ID card only records the card number;  An IC card, such as a Philips mifare card, can record about 1,000 characters.

D. Offline and network operation: Since there is no content in ID, the authority of the card holder and the system function operation should be fully dependent on the support of the computer network platform.  And the IC card itself has recorded a large number of user related content (card number, user information, authority, consumption balance and other large amount of information), completely can be separated from the computer platform operation, to achieve the network and offline automatic conversion mode of operation, can achieve a wide range of use, less wiring needs.

E. One-card extension application: ID card has no record, no partition, can only rely on network software to process the information of each subsystem, which greatly increases the dependence on network; If the user wants to add function points after the Id card system is completed, additional wiring is needed, which not only increases the difficulty of engineering construction, but also increases the unnecessary investment. Therefore, using ID card to do the system, it is difficult to expand the system, difficult to realize the real all-in-one card.

The IC card storage area itself is divided into 16 zones, each zone has a different password, with multiple sub-system management functions, such as the first zone to achieve access control, the second zone to achieve consumption, the third zone to achieve employee attendance and so on. Fully realize the purpose of one card, and can achieve complete modular design, even if the user wants to increase the function point, there is no need to wire, only need to increase the hardware and software modules, which is convenient for IC card system to upgrade and expand at any time, achieve smooth upgrade, reduce repeated investment.

F. System maintenance and operation:

For example, if a new user ID card is issued, it must be able to pass the network of the ID card system and manually download all ID card numbers to the pupil controller of each ID card one by one. Otherwise, the ID card can not be used as numerous cards; To change user permissions, enter the authorized ID card number on each ID card controller.

If the ID card is often added after the system is put into use, then every year a new card or modify the authority of a card, it is necessary to enter the card number on the controller available in the card, which greatly increases the workload and time of manual operation and maintenance; In addition, if there are more one-card subsystems or the subsystems are a little larger, the complexity of system maintenance and management increases geometrically. As a result, the system cannot run properly.

And the IC card system, IC card issued, the card itself is a data information carrier, even if the communication network is blocked, read and write controller as usual to achieve offline read and write card operation; If you change the user's authority, the user's authority can be written directly in the IC card, new users change the authority only need to modify the card, completely do not need to modify the controller, from the technical mechanism to avoid the manager everywhere to change the controller card permission problem, to improve management efficiency, to achieve the purpose of management.

G. Cost performance:

Although the ID card and its card reader is cheaper than the IC card and its card reader, but from the composition of the whole card system (wiring cost, structure composition), the price of the two systems is comparable, and the IC card system is more stable and reliable than the ID card system, so the cost performance of the IC card system is much higher than the ID card system.

In addition, considering the reality that the hardware environment of today's community is not very mature and the system personnel are not very familiar with the knowledge, it is impossible to establish or maintain a complete network system to support the 24-hour operation of the ID card. Therefore, it is a better choice for today's users to meet the mutual adaptation of online and offline running intelligence.
