The difference between IC and ID card for access control and attendance equipment

The difference between IC card and ID card
First, IC card and ID card definition IC card full name integrated circuit card (IntegratedCircuitCard), also known as smart card (SmartCard), can read and write, large capacity, encryption, data records, reliable, more convenient to use, such as card systems, consumer systems And so on, there are currently PHILIPS Mifare series cards.

ID card full name identification card (IdentificationCard), is a non-writable proximity card, with a fixed number, mainly SYRIS Taiwan's EM format, the United States HID, TI, MOTOROLA, and other ID cards.

Second, why the IC card to do initialization (ie, encryption) work, and ID cards do not use the 1.IC card, you must first pass the unique two-way key authentication between the IC card and the read-write device to perform related work, Therefore, the entire system has a very high security guarantee. Therefore, the factory IC card must be initialized (ie, encrypted) in order to generate an unbreakable one-card system key in the IC card after shipment to ensure the card system. Security release mechanism.

2. After the IC card is initialized and encrypted, it is passed to the user for use. The customer uses the IC card issuing system to generate a private key for each user's system card. This ensures that user cards issued in other user systems cannot be The use of the system ensures the specificity of the system, thus ensuring the safe use of the system.

3. ID cards, like magnetic cards, only use the "card number". In addition to the card number, the card does not have any security function. Its "card number" is open and bare. Therefore, the ID card is the "inductive magnetic card." , it is simply not necessary or does not require initialization.

4. Why isn't the initialization process done by the user? This is because:

1) If the user initializes himself, he/she cannot prevent the cheating inside the user. When the user uses the card system, if an employee uses the socially purchased card to initialize it at random, he can freely issue a household card that can be used by the household, or even Cards can be used to recharge cards, which will not only cause serious cheating consequences, but also lead to serious loopholes in the use of the card system security.

2) In addition, if the user purchases a defective factory card and initializes it and cannot use it on the system, it will cause the system to use poor performance or defects, which will cause the accident responsibility to be unclear.

3) The initialization process is performed in the factory, mainly the basic needs of the IC card security key authentication mechanism, and is also the IC card system integrator's profile. Just like the urban public transport IC card, these cards are used before being handed over to the public transportation system for use. The key of Zhang card must be controlled by factory encryption.

4) If the user loses the key card for initializing the authorization due to the lack of professional management, the user and the manufacturer will not be able to use the card. Therefore, the initialization work is done by the manufacturer to ensure security.
