7.P type IC card (parallel communication IC card)
Features:
1. Damage resistance and durability:
Smart cards use silicon chips to store information. The advanced wafer manufacturing process can fully guarantee the card's resistance to magnetism, static electricity and all kinds of ray. Moreover, due to the small size of the silicon wafers, there is an epoxy layer inside, and there are PCBs outside. The protection of the board and the substrate is therefore very resistant to mechanical and chemical damage. These are detailed in IS07816-1, and smart cards are now very sophisticated and durable. The information is stored for more than 100 years, and it is easy to read and write. The number of reads and writes is as high as 100,000 times. Even considering a variety of factors, a smart card can be used for at least ten years.
2. Storage capacity and flexibility:
The capacity of the smart card can be several bytes, and the storage area on the smart card can be divided and can have different access levels, which provides convenience for information processing and one-card use.
3. Encryption:
The smart card system has strong encryption, firstly embodied in the structure and read mode of the chip. The capacity of the smart card is large, and the read and write area of ​​the memory can be arbitrarily selected. Therefore, the flexibility is large even if the memory is general. Cards, using specific technologies, also have strong confidentiality. For cryptographic memory cards, there is a strict limit on the number of card password checks. If the number of cards exceeds the specified number, the card will be locked. The encryption of smart cards is also reflected in system design. Since smart cards are digital circuits that can be carried around, various hardware encryption methods of digital circuits can be used to improve the system's encryption. In addition, in software design, various encryption algorithms can be used to greatly enhance the security of the system.
The above is a superficial view on the concept of "one card" and its use. It is believed that the use of intelligent "one card" will certainly move toward a more practical and perfect situation.
"One-card use" and "one-card multi-use" have become the subject of application of smart cards today. As one of the largest IC card application areas in the country, the Urban Construction Card covers many areas such as city buses, subways, taxis, road and bridge tolls, water supply, gas supply, heating, residential areas, etc. TimeCOS/DI is in line with this. The application requires a smart card.
When such a smart card is used in a bank, it can insert a card reader to complete the banking business. At the same time, when using a bus or a taxi, you do not need to insert the card into the card reader. Simply swip the card over the card reader with the wireless sensor zone, which saves time. Therefore, as long as you have a “one card†in city life, you can call, take bus, play, shop, pay utility bills, and access cash.
