⒈ high reliability，
There is no mechanical contact between the contactless CPU card and the reader, which avoids various failures caused by contact reading and writing. For example, due to card insertion rough, non-card insertion, dust or oil caused by poor contact.
In addition, non-contact CPU card surface without bare chip, no need to worry about the chip off, electrostatic breakdown, bending damage and other problems, not only to facilitate the printing of the card, but also to improve the reliability of the use of the card.
Peal operation is convenient and fast
Due to the non-contact communication, the reader can operate within the range of 10cm card, no need to plug and unplug the card.
The user is very convenient to use.
No direction when using non-contact card, the card can be in any direction through the read-write surface
Operation, greatly improve the speed of each use.
Contactless card has a fast anti-collision mechanism, can prevent the data interference between cards. Therefore, the reader can handle multiple non-contact card CPU cards at the same time. This increases the parallelism of the application and actually increases the speed at which the system works.
Singled for multiple applications
The memory structure of contactless cards allows them to be used in multiple applications, and users can set different passwords and access conditions depending on the application.
Be careful with encryption
The serial number of the contactless card is unique and cannot be changed as the serial number is cured by the manufacturer before the product leaves the factory.
The contactless card and the reader use a two-way verification mechanism, that is, the reader verifies the legality of the CPU card.
At the same time the CPU the card also verifies the legality of the reader.
The contactless card should be mutually authenticated with the reader three times before processing, and encrypt all data during the communication process. In addition, each fan area in the card has its own operating password and access conditions.
