1. Security: IC card ID card card number is much larger than .ID card reader without any permission, easy-to-read data recorded in the imitation .IC card, write the corresponding password authentication is required, even cards Within each zone has a different password protection, comprehensive protection of data security, IC card write data read out password and password can be set to different hierarchical management provides a good way to ensure system security 2. Can record of: ID cards can not write data recorded content (card) can only be written once the chip manufacturer, developers only readable card to use, you can not develop a new system based on the actual number management needs of the system. IC card not only by authorized users to read large amounts of data, but also to write large amounts of data (such as a new card number, user permissions, user information, etc.) by an authorized user, IC card 3. recordings rewritable storage capacity:. ID card only record card number; and the content of the IC card (such as Philips mifare1 cards) can record approximately 1000 characters 4. offline and network operation: Because no content within the ID card, so the permissions of its card holders operating system functions to be completely depends on the computer network platform database support. The IC card itself has recorded a lot of user-related content (card number, user information, authority, balance and other large consumer of information), can be run from the computer platform, networked and offline automatic conversion operating mode, to achieve a wide range of use, less cabling needs 5. Expansion Card Applications:. ID card due to no records, no partitions, can only rely on network software to process the information for each subsystem, which greatly increased reliance on the network ; If, after the completion of the ID card system, users want to add functionality point, you will need additional wiring, which not only increases the difficulty of construction, but also adds unnecessary investment so that the use of ID cards to do the system, it is difficult for system expansion. difficult to achieve real card. The IC card storage area itself is divided into 16 partitions, each has a different password, with multiple subsystems independent management functions, such as access control to achieve the first partition, the second partition to achieve consumption, third Zoning achieve employee attendance, etc. The purpose of the full realization of the card, and can be completely modular design, even if the user to increase the function point, and without rewiring, simply increase the hardware and software modules, which facilitates the IC card system at any time in the future Upgrade extended to achieve a smooth upgrade, reduce duplication of investment, such as: a district has established a ID card card system, but because of the above drawbacks ID card system, the system can not be put into everyday use, so only the system is completely void, after the adoption 6. IC card card system maintenance and operation of intelligent systems: for example: Computer released a new user ID card, it must be through the network ID card system, with all the ID card number manually downloaded to each one ID card reader controller, otherwise the ID card as invalid card can not be used; To change user permissions, you need to have permission to enter the ID card number on each ID card controller Another example: In the system put into use frequently To add ID card, a card for each new or modified a piece of card privileges, you must enter the card number on the card is available for all controllers, which increases the workload
