An identification card membership card essentially for identification, Member confirmed, usually used Member malls, fitness centers, hotels, clubs, stores and other consumer sites. Non-contact card using non-contact IC card, also known as a passive IC card, also known as radio frequency IC card, IC card, is the IC chip, antenna composed of sensors, packaged in a standard PVC card within , the chip and the antenna without any exposed parts. A new technology is the world's developed in recent years, and its success will be radio frequency identification technology and IC card technology together to end the passive (no power supply card) and free access to this problem is the field of electronic devices a major breakthrough. Cards in a certain distance (typically 5-10mm) close to the surface of the reader, by passing radio waves to read and write data to complete the operation. 1, between the non-contact IC card and reader via radio waves to perform read and write operations. Communication between the two frequency of 13.56MHZ. Non-contact IC card itself is a passive card, when the card reader to read and write, the signal emitted by the reader superposition of two parts: one is the power signal, after the signal is received by the card, with its own L / C to produce a momentary energy to supply chips work. Another part is the instruction and data signals, command the chip to complete the read data, modify, store, etc., and the return signal to the reader, to complete a read or write operation. The reader is generally composed of single-chip, dedicated intelligence module and antenna, and is equipped with a communication interface with the PC, printer port, I / O ports, in order to be applied to different areas. 2, non-contact smart card internal partition contactless smart card inside is divided into two parts: the system area (CDF) user area (ADF) System area: used by card manufacturers and system developers and card issuers. User area: used to store data about the cardholder information. 3, compared with the contact card, contactless card has the following advantages: (1) High reliability: no mechanical contact between the non-contact card and reader, to avoid due to exposure to reading and writing The various failures. For example: As brutal card, non-card insertion of foreign objects, dust or oil resulting in poor contact caused by the failure. In addition, non-contact card surface without bare chip, need not worry about the chip off, static electricity breakdown, bending damage and other problems, both for card printing, but also improves the reliability of the card. (2) to facilitate the operation: Due to non-contact communication, the reader can be within the range 10CM operation of the card, so do not pluggable cards is very user-friendly. Not when the directional contactless card, the card reader can be swept surface in any direction, both to complete the operation, which greatly improves the speed of each use. (3) Anti-collision: the non-contact card fast anti-collision mechanism, to prevent interference of data between the card, so that the reader can "simultaneously" deal with more than one non-contact type card. This improves application parallelism, potentially improving system operating speed. (4) can be adapted to a variety of applications: non-contact card's serial number is unique, the manufacturer in the factory prior to curing this serial number, can not be changed. Using non-contact between the card and reader mutual authentication mechanism, namely to verify the legitimacy of IC card reader, but also to verify IC card reader legitimacy. Contactless card between pre-treatment to three times with the reader mutual authentication, and in the communication process all data is encrypted. In addition, the card each sector has its own operation password and access conditions. Memory structural features contactless card makes it a multi-purpose card can be used in different systems, depending on the application the user can set different passwords and access conditions. (5) Encryption performance: non-contact IC card by the IC chip, sensing antenna, and fully sealed in a standard PVC card, no exposed parts. Reading and writing process non-contact IC card, usually between the non-contact type IC card and reader via radio waves to complete the read and write operations. Non-contact type IC card itself is passive body, when the card reader reads and writes, the signal emitted by the reader superposition of two parts: one is the power signal, after the signal is received by the card, with its own L / C resonance, resulting in a momentary energy to supply chips work. Another part is the combination of the data signals, command the chip to complete the data, modification, storage, and returned to the reader. Read system consists of a non-contact IC card form, whether it is a hardware configuration, or the operation have been greatly simplified, and the help of advanced management software, offline mode of operation, all make the data read and write process easier.
