IC card is divided into contact IC card piece and non-contact IC card, now these two IC cards are popular smart cards, especially non-contact card IC card piece, now widely used in various fields. Contactless IC can also be called inductive card IC card, it is widely used mainly because of its advantages. Lets take a look at its advantages.
Where the advantages of contactless IC card
Contactless card IC card and contact IC and card compared to the advantages of contactless IC card is reflected in the following aspects.
1. Convenient and fast operation: Due to non-contact communication, the reader can operate within the range of 10cm card, so there is no need to insert the card, very convenient for users to use. Contactless card use without direction, the card can be in any direction by reading and writing to complete the operation, greatly improving the speed of each use.
2. High reliability: There is no mechanical contact between the non-contact IC card and the reader, which avoids various failures caused by contact reading and writing. For example, poor contact due to rough card insertion, non-card insertion, dust or oil, etc. In addition, there is no exposed chip on the surface of the non-contact card, so there is no need to worry about chip shedding, electrostatic breakdown, bending damage and other problems, which not only facilitates card printing, but also improves the reliability of the card.
3. Anti-conflict: Non-contact card has a fast anti-conflict mechanism, which can prevent data interference between cards. Therefore, the reader can "simultaneously; handle multiple contactless IC cards. This improves the parallelism of the application and actually increases the working speed of the system.
4. Can be applied to a variety of applications: The storage structure characteristics of contactless cards can be used in different systems, and users can set different passwords and access conditions according to different applications.
5. Good encryption performance: The serial number of the contactless card is unique, and the manufacturer solidifies the serial number before the product leaves the factory, which cannot be changed. Non-contact card and reader using two-way verification mechanism, that is, the reader to verify the legality of the IC card, time IC the card also verifies the legality of the reader. Before processing, the non-contact card and the reader should be three times mutual authentication, and in the communication process encrypt all data. In addition, each fan area in the card has its own operation password and access conditions, with the above unparalleled advantages, ideal for electronic wallets, automatic highway toll collection systems and bus automatic ticketing systems.
