Smart card is a kind of card use the silicon to store information, the state-of-the-art silicon production process can ensure the card is anti-magnetic, electrostatic, and has a variety of ray ability, and because of the small volume of silicon, there is epoxy layer of protection inside and there is the protection of the PCB board outside and the protection of the substrate. Therefore, the ability of resistance to mechanical and chemical destruction is strong. These have detailed requirements in the IS07816-1, and now the smart card has been done to be very exquisite and durable. Information retention period can be up to 100 years, and it is also easy to read and write, and the number of read and write cam be as high as 100,000 or more, even taking into account a variety of factors, a smart card can be used at least a decade or more.
The Flexibility of Smart Cards
The capacity of the smart card can be design to a few thousand bytes and the stored district on the smart card can be divided, it can have different levels of access and this offer great convenience for information processing and multi-purposes. This smart card if use in the bank, you can insert the card reader to complete the banking business. At the same time, in the bus or taxi use, without the card into the reader, simply Akira contactless ic card reader equipped with wireless sensing area you can look very saving time. Therefore, in the life of the city as long as there is a "card", you can call, take the bus, playing, shopping, pay utility bills and access to cash, the convenience is everywhere.
The Encryption of Smart Card
Smart card system has a strong encryption, first it is reflected in the structure of the chip and the reading mode, magnetic stripe card capacity is larger, and the memory reading and writing region can be arbitrarily selected, therefore, there is greater flexibility. Even as for the general memory card, if use a particular technology, it also has a strong confidentiality. As for the check card, there is a strict limit on the number of times for the password for encrypted memory card, if exceed the specified number of times, the card will be locked. Smart card encryption is also reflected in the system design, the smart card is a portable digital circuit, and the digital circuit hardware encryption means can be used to improve the system encryption. In addition, the software design, various encryption algorithms can be used, which greatly enhances the security of the system.
