IThe difference between IC card and ID card
A, IC card and ID card definition
IC card universal integrated circuit card (Integrated Circuit Card), also known as the smart card (Smart Card). Read and write, large capacity 1K bytes, the encryption function, reliability of data recording, more convenient to use, such as smart card system, consumption system, there are Mifare Ricardo PHILIPS.
ID card full name identification card (Identification Card), is a can not write card, containing a fixed number ID card can not be changed, mainly in Taiwan SYRIS EM format, USA HID, TI, MOTOROLA and other kinds of ID card.
Two, why the IC card to do initialization (i.e. encryption), and ID card no
The 1 IC card when in use, you must pass IC card and read-write equipment unique bidirectional key authentication, to carry out the relevant work, so that the whole system security has a very high. So, you must initialize the factory (that is, IC card encryption) is key card system in the IC card production factory the unbreakable, so as to ensure the safe payment mechanism of the smart card system.
The 2 IC card initialization encryption, to users, customers through the IC card issuing system, the private key of each user card to generate its own system. In this way, will ensure that the other users in the system of issuing user card cannot use the system, ensure that the specificity of the system, so as to ensure the safe use of the system mechanism.
3.ID card and magnetic card, just use the "card number, card number" in addition, without any security function, the "number" is open, exposed. So ID card is the "magnetic induction", it simply does not need or do not need initialization problem.
Why not 4 initialization process by the users themselves. This is because:
1) if the user‘s own initialization, cannot prevent users insider cheating. Because the user in the use of smart card system, if a staff with social bought card random initialization, which can be released into households to use household card, or even free to card charge value of consumption, which will not only cause serious cheating consequences, will also lead to safety card system loopholes exploited the use mechanism.
2) in addition, if users buy inferior factory card of your own initialization, and cannot be used in the system, will make the system performance is bad or paralysis, which will cause the accident responsibility is not clear.
3) initialization process in the factory, mainly is the basic need of IC card security key authentication mechanism, but also the IC card system integrators rules. Like the city public transportation IC cards, these cards to the public transport system, each card key encryption to have control of the factory.
4) if the user of the lack of professional management and the event lost initialization authorized by the key card, users and manufacturers will not be able to fill with the card. So, the initial work done by the manufacturers, only security.
Three, compare the IC card system and ID card system
1 security:
IC card security than ID card.ID card read the card number without any permission, easy to imitate the.IC card data read, write the corresponding password authentication is required, even of each district cards in different password protection, full protection of data security, IC card data password password and can read data set different, hierarchical management provides a good way, to ensure the system security.
2 recording:
ID cannot write data, the record contents (number) only by a write once chip manufacturing plant, developers can only read the card number to use, not for new numbers management system according to the actual needs of the system.
IC card can not only read a large amount of data by authorized users, but also by authorized users to write large amounts of data (such as a new card number, user permissions, user information such as IC card), erase the recorded content can be repeated.
The 3 storage capacity:
ID card only records the card number; and the IC card (such as Philips Mifare1 card) can record the contents of about 1000 characters.
4 offline and network operation:
No content within the ID card, so the card holder‘s permission, operating system functions to depend entirely on the computer network platform to support the database.
The IC card itself has documented a large number of user related content (card number, user information, authority, balance and other large consumer information), can run from the computer platform, operating mode to realize networked and offline automatic conversion, to achieve widespread use, less cabling requirements.
The 5 expansion card application:
ID card because no records, no partition, can only rely on the network software to handle the various subsystems of the information, which greatly increased reliance on the network; if the ID card system is complete, the user wishes to increase the function point, you will need additional wiring, which not only increases the difficulty of construction, and an unnecessary increase in investment so, the use of ID card system do, it is difficult for system expansion, it is difficult to realize a real card.
The IC card storage area itself is divided into 16 partitions, each partition has a different password, subsystems are independent management functions, such as the first district to achieve access control, second division third division staff attendance, consumption, and so on. The purpose of the full realization of card, and can be completely modular design, even if the user to increase the function point, also no longer wiring, simply increase the hardware and software modules, the IC card system easy to upgrade at any time, to achieve a smooth upgrade, reduce duplication of investment.
For example: a district has established the ID card card system, but because of the defects of ID card system, the system can not be put into everyday use, therefore the system completely invalid, after the card IC card system.
