IC cards, ID cards, M1 card, T5557 card, the encryption 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 2 Product editing IC card working principle is: 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 waves Excited, LC resonant circuit to resonate, so that with the charge within the capacitor; at the other end of this capacitor, then there is a single wizard-pass electronic pump, the capacitive charge to another within the capacitive storage, when the accumulated When the charge reaches 2V, the capacitor can be used as power supply operating voltage for the other circuits, will launch the card data reader out or receiving data. 3 Create workflow editor IC card production process is divided into: IC card from design to distribution, it 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 a common chip design considerations) 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 storage areas specific requirements
