Smart card concept definition Card gradually into our lives, a brief look at his pocket, we may carry the card with work permits and identity cards, there may be a calling card, with work permits can wander in and out of our office; but no identity can not fly, set Hotel room; using more and more popular in the streets of card phone booth, as long as Zhang phone card, we can quickly turn around the world ...... The reason why people are widely accepted and used a variety of cards, indicating that its use is widespread, and and people's daily lives. All of these store a certain amount of information (data) card-type object, we pass call data card, for storing information by way of electric or magnetic, so that the data read and write automated data card, called intelligent data card. 1970, Frenchman Roland Moreno (Roland Moreno) for the first time can be programmed to set the IC (Integrated Circuit) chip put in the card, so the card has more features. He was in the patent application for this invention has been described as follows: a can of self-protection on the memory card. Thus was born the world's first one IC card. In the following years, with the development of VLSI technology, computer technology and information security technology, etc., IC card technology has become more mature, and is currently abroad has been more widely used. 1993, various memory IC card sales 260 million, sales of smart IC card with a microprocessor to 35 million, is expected in 1996 will reach 800 million and 150 million, annual growth rate of 40%. Since the IC card appears, it has a variety of popular name internationally. English names are "Smart Card", "IC Card" and so on; in Asia, particularly Hong Kong and Taiwan regions, the multi-called "smart cards" "smart cards" and "smart cards" and so on; while in China, it is generally referred to for "IC card" or "smart card", collectively referred to herein as a smart card. Smart cards will have storage, encryption and data processing capabilities integrated circuit chip embedded in the plastic substrate, related to microelectronics technology, computer technology and information security technology, as a mature high-tech products, smart cards to improve the people's lives and the degree of modernization, has become one of a country's level of technological development signs. What is a smart card? Currently the industry is no unified, comprehensive definition, the following summarizes the common definition of a variety of information on a smart card on. 1) shape and a credit card, but contains a line with International Organization for Standardization (ISO) standards of integrated circuit chips (IC) on the card. 2) by one or more integrated circuit chips, and packaged into convenient for people to carry a card; has a temporary or permanent data storage capacity, the content is available for external read or for internal processing, it is judged; having a logical and mathematical operations processing capacity, and response information for identifying the chip itself and the externally supplied processing requirements. 3) IC card is the IC card. It is a development of semiconductor technology with increasing information and social security and other requirements came into being, with microprocessors and large capacity memory, such as integrated circuit chips and fitted onto a substrate made of plastic, etc. card. Its shape and general credit card to make a very similar, but slightly thicker. "IC card" and "magnetic", are both from a technical point of view from the name, it can not be, and "credit card", "Phone Card" from the application point of view, such as the naming of the card confused. For example, a credit card is a debit card issued by banks and other financial sectors, which can be made using the IC card, the card can also be made from the average user is not necessary to understand a credit card or IC card technology made of magnetic technology. Can be printed with color photos, graphics and explanatory text and other information on the IC card. Some of the security requirements of a higher IC card, printed on its surface a personal signature, holographic images and notes on a paper and similar security identification information. In accordance with ISO7816 international standard for contactless IC card provides that, in the upper left corner of the package IC card IC chip, which is covered with a 6 or 8 contacts and communicate with an external device, as shown below. wpe6095.gif (2081 bytes) IC card schematic According to ISO standards, some contacts and is defined as: Vcc: IC card working power; GND: ground; Vpp: Memory Programming Supply (optional); CLK: timing and synchronization-related signal; I / O: IC card serial data input / output; RST: Reset signal (optional); The remaining two contacts depending on different situations can be defined in the relevant application standards. |
