What are the differences between IC card and ID card?

First, the definition of IC card and ID card:


IC card, full name is integrated circuit card, also known as smart card . Read and write, large capacity, encryption, reliable data records, use more convenient, such as card systems, consumer systems.


ID card, full name is identification card, 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 IC card needs to do initialization (ie, encryption) work, and ID cards do not need it:


1. When the IC card is used, it must first pass through the unique two-way key authentication between the IC card and the read/write device before it can perform the relevant work, so that the entire system has a very high security guarantee. Therefore, the IC card must be initialized (ie, encrypted) in order to generate an unbreakable one-card system key in the factory IC card to ensure the secure distribution mechanism of the card system.


2. After the IC card is initialized and encrypted and passed to the user, the customer uses the IC card issuing system to generate a private key for each user's system card. In this way, it is ensured 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, use only the "card number". In addition to the card number, the card has no security function. Its "card number" is open and bare. Therefore, the ID card is the "inductive magnetic card." So basically it's not a question of whether it need to be initialized or not.
