The IC card itself has documented a large number of user-related content (card number, user information, authority,balance and other large consumer of information), can run from the computer platform, automatic conversion operation mode between networking and offline can meet the need of widespread use and less cabling.
5.Expansion applications of cards:
Due to no records, no partition, IC card can only rely on network software to handle the various the information of subsystems, which greatly increased reliance on the network; if the ID card system is complete, the user wishes to increase the function point, you will need additional wiring, This not only increases the difficulty of construction, and an unnecessary increase in investment. So ID card system is difficult for system expansion, it is difficult to achieve a real card.
The IC card memory area itself is divided into 16 partitions, each partition has a different password and independent management functions of multiple subsystems, for example the first district is to achieve access control, the second district is to achieve consumption, the third partition is to achieve employee attendance to realize the purpose of all-in-one card and complete modular design, even users want to increase the function point, no rewiring is asked, simply increase the hardware and software modules, it is good to upgrade and expand the IC card system at any time to achieve a smooth upgrade and reduce duplication of investment.
For example: a district has established the ID card systems, but because of the above-mentioned drawbacks, the system can not be put into daily use, so the system can only be completely nullified and changed to the use of IC card system.
6. Maintenance and operation of intelligent systems
For example: Computer released a new user ID card, the ID card number must be manually downloaded to the ID card reader controllers one by one through ID card network, or the ID card is not a valid card in use; to change user permissions, you need to enter each ID card controller with privileged ID card number.
