The smart card is the IC card, which combines microelectronic technology and computer technology and is widely used in the fields of finance, transportation, identity authentication, etc., and improves the modernization of people's life and work. The degree of comprehensive use of smart cards in intelligent buildings is an important indicator of the degree of intelligence of buildings.
This system adopts the most advanced non-contact IC card as the information carrier, and the card reading distance can reach 20 cm. In the card reading range, you only need to gently shake the card, you can complete the data exchange in an instant, eliminating the cumbersome, convenient and fast card insertion or card swiping; using mature technology and products, high reliability; can be used for one card, practicality Strong; the card and the card reader have no physical contact, and the failure rate is low; the WINDOWS operation interface is adopted, and the daily management operation is simple; the data encryption technology is adopted, and the security performance is high.
2 Non-contact smart card Contactless smart card, also known as RF card, completely encapsulates the chip and antenna inside the card. The surface of the card has no contacts and communicates with the reader through electromagnetic induction. Compared to contact smart cards, contactless cards have the following advantages:
(1) High reliability: There is no exposed chip on the surface of the non-contact card, which avoids physical damage caused by contact of the chip and facilitates printing of the card.
(2) Convenient and fast operation: The reader can operate the card from any direction within a certain distance range, flexible and diverse configuration. The reader can handle multiple smart cards at the same time.
(3) Good encryption performance: The contactless card must be mutually authenticated with the reader three times before processing, and all data is encrypted during the communication process.
The contactless smart card is the cutting-edge technology of the current international smart card. At present, the contactless smart card can be roughly divided into a logical encryption card and a CPU card according to different integrated circuits in the card. Since the CPU card is more secure than the logic circuit encryption card, the file management in the card is more effective, and the manner of realizing various functions is more flexible. The contactless logic encryption card conforms to the TYPE A standard and occupies most markets, and the contactless CPU card The TYPE B standard is generally adopted.
3 integrated IC card management system program integrated IC card management system includes intelligent parking lot management system, IC card access control management system, IC card attendance management system, IC card restaurant consumption system and other subsystems. Each subsystem has its own data area and security code and corresponding management software, which can be independently counted and accounted for. At the same time, it is also connected with other management systems of the building. For example, the intelligent management subsystem of the parking lot has its own charging management station, which belongs to the comprehensive parking management system of the parking lot, and can exchange data with the Finance Department through the network. Another example is the IC card access control management system. It is not only an integral part of the integrated IC card management system, but also a security monitoring system.
