The Type and Characteristics of the Smart Card

The types of smart card

First, encrypted memory card (Security Cards-contact) Second, non-encrypted memory card (Memory Cards-contact) Third, prepaid card (Prepayment Cards-contact) Fourth, CPU card (Smart Cards Contact type) Fifth, RF encryption card (RF1D non-contact card) Sixth, RF CPU card (RFID non-contact card) Seventh, P type IC card (Parallel communication IC card)

RFID PROXIMITY GOLD CARD

The characteristics of the smart card

First, anti-destructive and durability: Smart card(magnetic stripe card) is to store the information with the use of silicon, and the state-of-the-art silicon production process can ensure the anti-magnetic, electrostatic, and a variety of ray ability of card, in addition, because of the small volume of silicon, there is the epoxy layer of protection inside and there are PCB plate and substrates protection outside. Therefore, the resistance to mechanical and chemical destruction is strong. There are detailed provisions in the IS07816-1. The smart card has been very exquisite and durable. More information can be saved for more than 100 years. And it is easy to read and write, and the number of read and write can reach as high as 100,000 or more, even taking into account a variety of factors, a smart card can be used at least more than a decade.

Second, storage capacity and flexibility: The capacity of the smart card can reach a few dry bytes and the stored area on the smart card can be divided, and there are different levels of access, which provides a convenient for information processing and multi-purpose card.

Third, the character of encryption: The smart card system has the strong encryption, and it is firstly reflected in the structure of the chip and the reading mode, the capacity of the smart card is larger, and the memories read and write region can be arbitrarily selected. Therefore, it has the greater flexibility, even if the ordinary memory card with the use of a specific technology, but also has strong confidentiality. smart card manufacturer said that for the encrypted memory card, there is a strict limit on the number of times for the check of card password and the card will be locked if it exceeds the specified number of times. The encryption of the smart card is also reflected in the system design, for the smart card is a portable digital circuit, and the various hardware encryption means of digital circuit can be used to improve the system encryption. In addition, in the software design, various encryption algorithms can be used, which can greatly enhance the security of the system.

www.lbdtech.com always upholds the spirit of "people-oriented, and technology is the core". Set quality as fundamental strategic, we continuously innovate and use advanced production equipment and strong technical force to strictly manage production, to strengthen quality control, and to strive to provide satisfaction high quality products for the majority of users.
