An integrated circuit IC card is a smart card that integrates circuits and storage chips, also known as a smart card, chip card or IC card. It is a card with storage, processing and communication functions. It can be used to store various data such as personal information, financial information, health information, and transmit and process data through interaction with the card reader. IC cards are widely used in finance, communications, transportation, medical care, education and other fields, and are an indispensable smart card in modern society.
The organizational code of the IC card integrates a variety of technologies and functions, including chip manufacturing technology, packaging technology, communication protocols, data encryption algorithms, etc. The chip manufacturing technology of the IC card is the core technology of the IC card, including chip design, manufacturing, testing and packaging processes. Chip design is the key link of the IC card, which determines the function and performance of the IC card. Chip manufacturing is the basic process of the IC card, including chip growth, etching, ion implantation, metallization and other processes. Chip testing is the quality assurance link of the IC card, and through testing, it can be ensured that the function and performance of the chip meet the requirements. Chip packaging is the shell manufacturing process of the IC card, which encapsulates the chip in a plastic card to protect the chip from damage.
The communication protocol of IC card is the specification for data exchange between IC card and card reader, including physical layer, data link layer, network layer and application layer. The physical layer is the physical connection between IC card and card reader, including interface type, transmission rate, transmission distance, etc. The data link layer is the data transmission protocol between IC card and card reader, including data frame format, error detection, flow control, etc. The network layer is the network protocol between IC card and card reader, including data packet format, routing selection, congestion control, etc. The application layer is the application protocol between IC card and card reader, including data exchange format, data processing rules, security mechanism, etc.
The data encryption algorithm of IC card is the security technology of IC card, which is used to protect the data in IC card from illegal access and tampering. Data encryption algorithms include symmetric encryption algorithm, asymmetric encryption algorithm, hash algorithm, etc. Symmetric encryption algorithm is a commonly used encryption algorithm in IC card, which encrypts and decrypts data with a key. Asymmetric encryption algorithm is a public key encryption algorithm in IC card, which encrypts and decrypts data with public key and private key. Hash algorithm is a data integrity verification algorithm in IC card, which generates a summary by performing hash operation on data, which is used to verify the integrity of data.
In general, an IC card is a smart card that integrates circuits and memory chips, and has storage, processing and communication functions. The organization code of the IC card is the unique identifier of the IC card, which is used to distinguish different IC card products. The IC card integrates a variety of technologies and functions, including chip manufacturing technology, communication protocols, data encryption algorithms, etc., to ensure the security and reliability of the IC card. IC cards are widely used in finance, communications, transportation, medical care, education and other fields, and are an indispensable smart card in modern society.
