Difference: ID card can only read and cannot write, while IC proximity key fob card can read and write data, and proximity key Fob can be encrypted. The contactless proximity key Fob has read and write functions. There are 16 sectors that can be encrypted. The ID card can be copied by people. The IC involves sector passwords. Compared with the security performance, it is not easy to be cloned. Therefore, the IC door card on the market is better than the ID card. The price is more expensive.
1. Definition of IC door card and ID card
The full name of IC door card is Integrated Circuit Card, also known as Smart Card. Read and write, large capacity, encryption function, reliable data recording, and more convenient to use, such as all-in-one card systems, consumer systems, attendance systems, etc. At present, there are mainly PHILIPS Mifare series cards.
The full name of ID card is Identification Card. It is a non-writable proximity card with a fixed number. It mainly includes EM format of Taiwan SYRIS, American HID, TI, MOTOROLA and other ID cards.
2. Why does the smart door card have to be initialized (ie, encrypted), but the ID card is not used?
1. When the door entry proximity key Fob is in use, it must pass the unique two-way key authentication between the proximity key Fob and the reading and writing device before relevant work can be carried out, so that the entire system has a very high security guarantee. Therefore, the factory-factory proximity key Fob must be initialized (ie, encrypted). The purpose is to generate an unbreakable one-card system key in the factory-factory proximity key Fob to ensure the security issuance mechanism of the one-card system.
2. After the proximity key Fob is initialized and encrypted, and when it is handed over to the user, the customer uses the proximity key Fob issuance system to generate a private key for each user card. In this way, it is ensured that user cards issued in other user systems cannot be used in this system, the specificity of the system is guaranteed, and the safe use mechanism of the system is guaranteed.
3. The ID card, like the magnet proximity key Fob, only uses the "card number". In addition to the card number, there is no confidentiality function in the card, and the "card number" is public and exposed. Therefore, the ID card is an "inductive magnet proximity key Fob", and there is no question of whether it needs to be initialized or not.
