Detailed explanation about the contactless IC card
Recently there are a lot of customers friend call the company know the related information of contactless IC card, for this kind of situation, our company technical department incorporates information about contactless IC card, for customer's further understanding friends.
Rf CARDS, contactless IC card is also called consists of IC chip antenna, induction, encapsulated in a standard PVC card inside, without any chip and antenna exposed portion. Is one of the world in recent years developed a new technology, it will success of radio frequency identification technology and IC card technology combined, no end of source (card without power supply) and contactless this difficult problem, is a breakthrough in the field of electronic devices. The card in the scope of a certain distance (usually 5-10 mm) close to the surface of the read-write device, done through radio waves to transfer data read and write operations.
1. The non-contact IC card and card reader via radio waves to finish read and write operations. Communication between the frequency of 13.56 MHZ. Non-contact IC card itself is passive, when read/write device to read and write operations is card read-write device signals formed by superposition of two parts: one part is power signal, the signal received by the card after the L/C with itself to produce an instant energy to supply the chips work. The other part is the instruction and data signal, command chip to complete the data read, modification, storage, etc., and return to read and write device signal, to complete a read or write operation. Read/write device is generally by the single chip microcomputer, intelligent module and antenna, and is equipped with communication interface with PC, print, such as I/O mouth, in order to applied in different fields.
2. The non-contact smart card internal partition
Non-contact smart card inside is divided into two parts: the system area (CDF) user area (ADF)
System area: by the card manufacturers and system developers and card issuers.
The users area: to hold the cardholder's information about data.
3. Compared with the non-contact IC card, contactless card has the following advantages:
(1) high reliability of contactless IC card and the read/write device, no mechanical contact between avoided due to exposure to read and write and produce all kinds of trouble. Such as:
Due to rough card, the card insert foreign object, dust or oil pollution caused by lead to poor contact failures. In addition, the surface is bare chip contactless card, do not need to worry about chip off, electrostatic breakdown, bending damage problems, convenient for card printing, and improve the using reliability of card.
2 it is easy to operate
Due to the contactless communication, reading and writing device can operate it on card within 10 cm, so you don't have call waiting, convenient user use. Non-contact card no direction, when using a card can be in any direction over the surface of the read-write device, can complete the operation, which greatly improve the speed of each use.
(3) the conflict
With rapid anti-collision mechanism in non-contact card, can prevent the card data interference between, therefore, can read and write device "and" handling more contactless IC card. It can improve the application of parallelism, virtually improve the system work speed.
(4) can be suitable for many applications
Non-contact card serial number is unique, manufacturer before the products leave the factory has put the serial number curing, shall not be changed. Non-contact between the card and read/write device adopts two-way authentication mechanism, to verify the legitimacy of the IC card read and write device, and also verify the legitimacy of the read/write device IC card.
Non-contact card before processing with three mutual authentication between read and write device, and all the data are encrypted in the communication process. In addition, the card in each sector has its own operation passwords and access conditions.
Contact card memory structure characteristics make it a card holders, can be used in different systems, the user can according to different application set different passwords and access conditions.
5] encryption performance is good
Contactless IC card by the IC chip, induction of antenna, and completely sealed in a standard PVC card, no exposed portion. Contactless IC card read and write process, usually by a non-contact type IC card and read/write device to finish read and write operations by radio waves.
Non-contact type IC card itself is passive, when read/write device to read and write operations card read-write device signals formed by superposition of two parts: one part is power signal, the signal from the card after receiving L/C to produce resonance with itself, to produce an instant energy to supply the chips work. The other part is combined with the data signal, command the chip data, modification, storage, etc., and return to read and write. Formed by the non-contact IC card read-write system, both hardware structure, and operation process is much simplified, has been at the same time with the help of the advanced management software, can the operation of the offline mode, all data read and write process simpler.
High temperature resistant induction card
In order to meet the demand of practical application, we constantly develop adapt to special application environment of the high performance induction card, in the high temperature resistance, flexural and using environmental protection material, compound and into, we adopt imported high temperature resistant materials with superior properties of high temperature resistance, folding, in the high temperature exposure is not easy to deformation, does not affect the function, cooperate with our induction card read-write device, is widely used in highway charge and management to the community.
