IC card IC card (Integrated Circuit Card, IC card), also known as smart cards (Smart card), smart cards (Intelligent card), a microcircuit card (Microcircuit card) or microchip cards. It is a micro chip embedded in the card base in line with ISO 7816 standards in the form of a card made. Communication between IC card and reader can be a contact or non-contact. The communication interface to the IC card into a contactless IC card, contactless and dual interface IC card (along with contact and non-contact communication interface). IC card information because of its inherent security, portable, quite perfect the advantages of standardization in the field of authentication, banking, telecommunications, public transport, parking lots and management is being more and more applications, such as second-generation ID cards, bank The electronic wallet, Telecom's mobile phone SIM cards, public transport bus card, subway card, collect parking fees for parking cards, etc., all play an important role in people's daily lives. IC card information carrier is yet another card after appearing. IC card is an IC card, usually with a bus card is an IC card and general common IC card using radio frequency technology and support IC card reader communication. IC card and magnetic card is different, IC card information stored by the integrated circuit card, and card information is recorded by the magnetic card. Cost IC card is generally higher than the card, but better confidentiality. Non-contact IC card, also known as radio frequency card, successfully resolved a passive (no power supply card) and avoid contact with this problem, it is a major breakthrough in the field of electronic devices. Mainly used for transportation, telecommunications, banking, yard management. The main features include secure authentication, electronic wallets, data storage. Common access cards, second-generation ID card belonging to security certification applications, and bank card, subway card is the use of an electronic wallet function.

Fundamentals 1 Product Principle IC card work are: RF IC card reader to send a fixed frequency of electromagnetic waves, the card has a series resonant LC circuit, its frequency and the same frequency emitted by the reader, so that the electromagnetic excitation next, LC resonant circuit to resonate, so that with the charge within the capacitor; at the other end of the capacitor is connected with a single conduction electron pump, and the capacitive charge to another within the capacitive storage, when the accumulated charge reaches 2V, the capacitor can be used as power supply operating voltage of other circuits, will launch the card data reader out or receiving data. 2 production process IC card production process is divided into: IC card, from design to distribution, can be summarized as the following steps: design of the card depending on the application system functionality and security requirements of the design card chip (or consider the design of general-purpose chip), and according to the technical level and cost of the smart card MPU, memory capacity and COS specific requirements, or to assign logic encryption card logic functions and store specific requirements. Similar card design process and IC design ASIC (application specific integrated circuit) design, including logic design, logic simulation, circuit design, circuit simulation, layout and correctness verification, by means of Workview, Mentor or Cadence and other computer aided design tools. For smart cards, often used in foreign countries as the industry standard microprocessor core, adjust the type and capacity of the memory, without having to re-design. More feasible approach is the domestic design COS, the foreign semiconductor manufacturers to produce chips for the sake of reliability, these chips should have self-protection. Software Design (adapted for smart cards only) include COS and application software design, there is a corresponding development tools available. Due to security and smart card COS, and therefore an important economic sector in the country and the smart card confidential departments should write Chinese designed by COS. Chip manufacturing production circuit designer on the single crystal silicon wafer will be designed or COS territory of code submitted to the fab. According to the requirements of the design and manufacturing process, resulting in a multi-layer mask. On a wafer can produce several hundreds to thousands of independent circuits, each is a small chip. Apart from a small piece by IC card standard (8 contacts) designed pad, there should be a probe specifically for testing compacts, but pay attention to whether these compacts give attackers an opportunity to exploit . Computer test and write information using a belt test program in the E2PROM control of each chip on the wafer probe test. Defective chips in the mark, writes factory tested code and other information in the chip. If the user needs to write to the E2PROM factory, and we can at this time. Transportation Code can be written at this time. Transport code is to prevent the cards in transit from the factory to the publisher's stolen and take defensive measures, are only manufacturers and distributors to know the password. After receiving the card issuers should first check the transportation code, such as checking is not correct, the card will be self-locking, blown fuses. Mill cut wafer thickness to comply with IC card will be cut into many small chip wafer polishing. Making the micro-fabricated chip module mounted on the eight contacts of the printed circuit sheet, called micro-module. Card manufacture micro module embedded in the card, and to complete the printing job card surface. Card initialization code to check transport. As for the logic encryption card, transportation code can be written to the user's password factory area, after checking the correct publisher rewritten user password for the smart card, then you can write passwords, keys, document and other operations. Operation is completed, the fuse has blown. Thereafter the card into the user mode, and can never return to previous work, do so in order to ensure the safety card. Processing issued by the issuer of the card reader device personalization process, writing some of the information required by the application. After the above card these processes, it becomes a uniquely identifies the user's card, you can give users.
