IC CARD
The full name of the IC card is“Integrated Circuit Card“.
IC Card Universal Integrated Circuit Card (Integrated Circuit Card),
also known as Smart CARDS (Smart Card). Read/write, large capacity, encryption, data record,
reliable and more convenient to use, such as cartoon systems, consumer systems, etc.,
Generally used for access control (RFID Cards)and door phone system.
ID CARD
ID Card for Identification Card (Identification Card), is a kind of not write induction Card,
including fixed number
What is the difference between an IC card system and an ID card system?
1. Security: The security of the IC card is much larger than that of the ID card.
The card number in the ID card is read without any permission, and it is easy to copy.
The data recorded in the IC card is read and written, and the corresponding password authentication or even the card is required. Each zone has different password protection, which fully protects data security. The password of the IC card to write data and the password of the read data can be set differently, providing a good hierarchical management method to ensure system security.
2. Recordability: The ID card cannot write data, and its recorded content (card number)
can only be written by the chip manufacturer once. The developer can only read the card number and use it. It is impossible to formulate a new number management system according to the actual needs of the system. The IC card can not only be The authorized user reads a large amount of data, and can also write a large amount of data (such as a new card number, user's authority, user data, etc.) by the authorized user, and the content recorded by the IC card can be repeatedly erased.
3. Storage capacity:
The ID card only records the card number; and the IC card
(such as the Philips mifare1 card) can record about 1000 characters of content.
4. Offline and networked operation:
Since there is no content in the ID card,
the card holder's authority and system function operation depend entirely on the support of the computer network platform database. The IC card itself has recorded a large amount of user-related content. (Card number, user data, permissions, consumption balance, etc.), can completely run away from the computer platform, to achieve the operation mode of networking and offline automatic conversion, to achieve the needs of a wide range of use, less wiring.
5. One-card expansion application:
The ID card has no record, no partition can only rely on network software to process the information of each subsystem, which greatly increases the dependence on the network; if the ID card system is completed, the user wants to increase the function point. , additional wiring is required, which not only increases the difficulty of engineering construction but also increases unnecessary investment. Therefore, using an ID card to do the system is difficult to expand the system, and it is difficult to realize the real card. The IC card storage area itself is divided into For 16 partitions, each partition has a different password, with multiple subsystem independent management functions, such as the first partition to achieve access control, the second partition to achieve consumption, the third partition to achieve employee attendance, etc. to fully realize the purpose of the card, and It can be completely modularized. Even if users need to add function points, there is no need to re-route, just add hardware and software modules, which is convenient for the IC card system to upgrade and expand at any time, achieve smooth upgrade and reduce repetitive investment. For example, The ID card system has been established in the community. However, due to the above drawbacks of the ID card system, the system cannot be put into daily use,
so the system can only be completely abolished. Card IC card system.
6. Maintenance and operation of the intelligent system:
For example, if the computer issues a new user ID card, it must manually download all the ID card numbers to each ID card reader controller through the network of the ID card system. Otherwise, the ID card is not used as an invalid card; if you want to change the user rights, you need to enter the ID card number with permission on each ID card controller. For example: often add the ID card after the system is put into use. , each time you add a card or modify the permissions of a card, you must enter the card number on all controllers available on the card, which increases the workload.
