Non-contact IC card is also called radio frequency card, the IC chip, induction antenna, packaged in a standard PVC card, the chip and the antenna without any exposed parts. The world in recent years developed a new technology, its success will be radio frequency identification technology and IC card technology together, the end of the passive (no power supply card) and free access to this dilemma is the field of electronic devices a major breakthrough. card in a certain distance range (typically 5-10mm) close to the reader the surface of the transmission by radio waves to complete the reading and writing data.
1. Non-contact IC card and the reader via radio waves between the read and write operation to complete. Frequency of communication between the 13.56MHZ. Non-contact IC card itself is passive cards, when the reader to read and write operations on the card, the reader signals composed by the superposition of two parts: one is the power signal, after receiving the signal from the card with its own L / C to produce a work of instant energy to supply chips. The other part is the instruction and data signals for data read command and chip, modification, storage, and returns the signal to the reader, to complete a write operation. Readers are generally single chip, dedicated Smart module and antenna, and with communications with the PC interface, printer port, I / O port, in order to apply to different areas.
2. Contactless smart card internal partition
Non-contact smart card inside is divided into two parts: the System area (CDF) User Area (ADF)
System area: from the card manufacturers and system developers and card issuers use.
User area: used to store the cardholder data.
3. And contactless IC card compared to non-contact card has the following advantages:
⑴ reliable non-contact IC card and the reader had no mechanical contact, avoid contact with read and write and produce a result of various failures. For example:
As the brutal card, non-card insert foreign objects into, leading to poor contact caused by dust or oil failure. In addition, non-contact chip card surface without nudity, do not worry about chip off, static electricity breakdown, damage and other problems bending, both for card printing , and also enhance the reliability of the card.
⑵ easy to operate
As the non-contact communication, within the reader in the 10CM can operate on the card, so do not pluggable card, very easy to use. Contactless card without direction, the card can flash reader in any direction of the surface can accomplish the operation, which greatly improves the speed of each use.
⑶ anti-collision
Non-contact card in a fast anti-collision mechanism, to prevent interference of data between cards, so readers can "also" deal with more than one non-contact IC card. This has increased the application of parallelism to improve the system virtually pace of work.
⑷ for a variety of applications can be
Non-contact card is the only serial number, manufacturer product factory in this sequence number before curing, can not be changed. Contactless card and reader authentication mechanism between the two-way, that reader authentication IC the legitimacy of the card, and IC card reader also verify the legitimacy of.
In dealing with non-contact card reader before and three times between the mutual authentication, but also in the process of all data communications are encrypted. In addition, the cards operate in all sectors have their own password and access conditions.
Contact structural characteristics of the memory card to make it a multi-purpose card can be used in different systems, different applications the user can set different passwords and access conditions.
⑸ encryption performance is good
Non-contact IC card by the IC chip, induction antenna, and fully sealed in a standard PVC card with no exposed parts. Non-contact IC card reading and writing process, usually by non-contact type IC card and reader through radio waves between the read and write operation to complete.
Non-contact type IC card itself is a passive body, when the reader on the card read and write operations, read and write signals emitted from the stack composed of two parts: one is the power signal, the signal received by the card after his own L / C generated resonance, produces a momentary power supply chips to work. The other part is combined with data signals, command and chips for data, modification, storage, and returned to the reader. By non-contact IC card reading and writing formed the system, whether hardware or operation have been greatly simplified, while the help of advanced management software, offline mode of operation, all the data read and write process easier.
Temperature sensor card
To meet the practical needs, we constantly develop the special high-performance sensor card application environment, in high temperature, bending and using environmentally friendly materials, we made use of imported high-temperature composite materials, with high temperature resistance, superior folding characteristics , in front of high-temperature exposure is not easy deformation, does not affect the functional properties, with our proximity card reader, widely used in highway toll and district management. |
