What Are the Different Types of Smart Card Software?

Smart Card: A general term for a plastic card (usually the size of a credit card) with a microchip embedded in it. Some smart cards contain a microelectronic chip, and the smart card needs to perform data interaction through a reader. The smart card is equipped with CPU, RAM and I / O, which can process a large amount of data by itself without disturbing the work of the host CPU. Smart cards can also filter erroneous data to reduce the load on the host CPU. It is suitable for occasions with a large number of ports and fast communication speed requirements. The integrated circuit in the card includes a central processing unit CPU, a programmable read-only memory (EEPROM), a random access memory (RAM), and a chip operating system (COS) operating in the ROM. The data in the card is divided into external reading and internal processing.

What is the purpose of smart cards?

Functionally, the use of smart cards can be classified into the following four points:

1. Identification-use the included microcomputer system to perform mathematical calculations on the data to confirm its uniqueness.

2. Payment tools-built-in

In 2011, China's IC card sales revenue was about 9 billion yuan, an increase of 11.1% over 2010, and the number of sales reached 2.43 billion, an increase of 13.6% over the previous year, a record high. It is estimated that in the next three years, China's IC card industry is expected to grow at a rate of about 14%. By the end of 2011, China's telecommunications sector had purchased a total of about 6 billion IC cards, making it the number one IC card consumer market in China. In 2011, the number of Chinese mobile subscribers reached 990 million, and the penetration rate of mobile subscribers was 72.0%. At the same time, China's SIM card market issued 890 million cards. As the penetration rate of mobile subscribers further rises, the growth rate of China's SIM cards will gradually slow down and eventually enter a stable period in the next 3-5 years. In the next two years, China's second-generation ID card market will be in a stable period of card issuance. However, the expiration of the first batch of second-generation certificates (ten-year validity) in 2014 will once again drive the growth of China's ID card market. As of the end of 2011, the cumulative issuance of China's social security cards was only 190 million, with a penetration rate of less than 14%. According to the Ministry of Human Resources and Social Security, the issuance of China's social security cards is expected to reach 610 million during the 12th Five-Year Plan period. Therefore, it is expected that China's social security card issuance volume will increase by 2015.

In addition, China's financial IC card, health card, mobile payment, and city card IC and other IC card market segments, with the support of government policies and market promotion, are also expected to generate greater growth.

advantage

1Easy to carry around: the light card can be conveniently placed in a wallet or card bag and can be mailed.

2 Large storage capacity: one card can hold 4-6 megabytes of information. No other portable information medium (magnetic card, IC card, microfilm) can be compared with it.

3High reliability and high security of information recording: Because it is a laser-perforated recording method, the card is not afraid of any electrical / magnetic interference, and has a strong resistance to water, pollution and extreme temperature changes. Anyone trying to change the content of the information on the card in any way must leave a trace.

4 High confidentiality: Canon optical card has a unique design of optical card information security measures, which can be used for one card and one code, which cannot be read by conventional methods, and it cannot be deciphered.

5 Relatively cheap

In the following, IC cards will be classified and analyzed in detail from different perspectives.

The smart card and IRD voltage are 3V 5 V ± 10%, which is 2.7 V to 5.5 V. The GSM smart card is also 5V, but the other parts inside the phone are 3V, so there is an additional voltage conversion part with the smart card.

The internal operation of the card has its software in addition to the hardware, and usually requires a kernel
