A)The definition of IC cards and ID cards
The full name of IC card is integrated circuit card IC card, also known as smart card, Can read and write, with large capacity, encryption function, reliable data recording, more convenient use, such as all-in-one card systems, consumer systems, currently PHILIPS and Mifare series cards are available.
The full name of ID card is identification card, a non-written sensor card, containing a fixed number, there are Taiwan SYRIS EM format card, the United States HID card, TI, MOTOROLA and other types of ID cards
B)Why do IC card need initialization (ie encryption), while the ID card not
1. While using IC card, it can work only after the password is firstly two-way authenticated between IC card and reader device, so that the whole system has a very high security. Therefore, we must initialize the factory IC card (ie encryption) in order to generate unbreakable key card system after into market to ensure the security of card outgiving mechanism.
2. After IC card initialized and encrypted, the users create special private key for their own system through the IC card issuing systems that guarantees those card issued by other users system can not be used in this system and ensure the specificity of the system to ensure the safe use mechanism of the system.
3. ID card is the same as magnetic card simply using the "card number", without any security function in addition to card number, and the "card number" is open and exposed. So an ID card is exactly a "magnetic sensor card", initialization is absolutely no necessary.
4.Why initialization is not done by the users? This is because of:
1) If initialization done by users, fraud can not be prevented inside the staff of users. Because when using the card system, if one employee randomly initialize the card bought from the community, and turn it into a household card only used by resident, even recharge card to consume, which will not only cause serious cheating consequences, will also lead to serious flaws of use mechanism.
2) In addition, if users initialize those low-grade cards that can not be used in the system, poor system performance or paralysis will happen, which will result in unclear responsibility for the accident.
