IC card is another new information tool after magnetic card, which refers to integrated circuit card. Bus card is a kind of IC card. The common IC card uses RF technology to communicate with IC card reader. According to its structure, IC card can be divided into general memory card, encrypted memory card, CPU card and super smart card. 1. Memory card, whose embedded chip is equivalent to ordinary Serial EEPROM memory, has the advantages of convenient information storage, simple use, low price of IC card, and can replace magnetic card in many occasions. However, because it does not have the function of information security, it can only be used in applications with low security requirements. 2. The logic encryption card and the encryption memory card are embedded with chips, and the control logic is added outside the storage area. Before accessing the storage area, the password needs to be checked. Only the password is correct, can the access operation be carried out. This kind of information has good confidentiality. 3. CPU card, with chip embedded in the card, is equivalent to a special type of single-chip microcomputer, which has not only controller, memory, timing control logic, but also algorithm unit and operating system. Because CPU card has the characteristics of large storage capacity, strong processing capacity, information storage security and so on. It is widely used in the situation where information security requirements are particularly high. 4. Super smart card, which has MPU and memory, keyboard, LCD and power supply, is rare. IC card is divided into contact IC card and non-contact IC card according to the different interface of data exchange with the outside world. The contact IC card can read and write data after the contact of the IC card reading and writing device contacts with the contact of the IC card. The international standard ISO7816 has strict regulations on the mechanical and electrical characteristics of such cards. The contactless IC card has no circuit contact with the IC card equipment, but read and write through the contactless read and write technology, which successfully solves the problem of passive and contactless, and is a major breakthrough in the field of electronic devices. In addition to CPU, logic unit and memory unit, the embedded chip adds RF transceiver circuit. This kind of card is generally used in the automatic toll collection system of public transportation, ferry, subway and other occasions with frequent use, relatively less information and high reliability requirements. At present, the most common contactless IC card in the market is contactless logic encryption card. With its good performance and high cost performance, this kind of IC card has been favored by the majority of users, and has been widely used in public transport, medical treatment, access control and other fields. Because the non-contact logic encryption card chip adopts the stream cipher technology and the key length is not very l...

The annual CES (Consumer Electronics Show) opened in Las Vegas on January 6, 2016. As a world-renowned science and technology event, the concepts discussed in CES will become a hot topic in the next two to three years. However, in this CES, which seems to have no core theme, there are many things that are observed by interested people: the Internet of things, smart home, virtual reality, etc. More importantly, the combination of Internet of things and cloud computing. "Lazy economy" is being talked about by more and more people, or will become the new economic growth point of smart home in the next few years. An interesting phenomenon is that the concept of the lazy economy is very popular both at home and abroad. Although o2o has been used for many times since the beginning of the year, and now it has been slightly eased, the concept never seems to cool down. As Shahid Ahmed, a senior executive of PWC, said, "in the field of Internet of things, we have reached a turning point: the integration of consumer experience, digital technology and sensor technology." Fortunately, with the continuous development of related technologies, the smart home industry based on the home Internet of things can capture the "lazy economy" as a new growth field - the convenient life at your fingertips, which is the choice of the middle class who cares about saving time and is willing to try. What's more, "lazy people" are not idle, but to further liberate more time and energy to invest in more worthy areas. This coincides with the original intention of smart home interest: to make people's lives truly free and convenient through technology. What the "lazy man" requires is to work out the most reasonable scheme by intelligent calculation according to the actual situation in the simplest operation as possible, and to realize the requirements of accuracy and complexity as efficiently as possible. This requires not only technical support, but also the thinking close to the user's actual experience, otherwise it will become a chicken ribs. In fact, in the smart home industry, sharp manufacturers at home and abroad have caught the pass of this node, and timely launched a variety of products that are convenient for the user's life: sweeper robot, automatic fast food machine, intelligent lighting adjustment, intelligent door lock, etc. In terms of smart door lock, this CES is like the W2 walnut smart lock of CEI, which realizes the remote door opening and closing service of "cloud key", and provides a good experience for "lazy people" to break the space limit. It is worth noting that local excellent original manufacturers also have outstanding performance in the field of smart home, and they have also upgraded and fermented in the domestic market in recent years. There is no doubt that smart home based on "lazy economy" has great development potential. According to the latest report released by research and markets, it is predicted that the global smart home market will grow ...
