英文及翻译 IC classification IC card is referred to the IC card. IC card and magnetic card the same size in the top left of their cabinets have one or more integrated circuit chips. Chip is generally not volatile memory (ROM, EPROM, EEPROM), the protection of logic circuits, even the CPU (central processing unit). IC chips with written data and the ability to store data, IC card memory contents can be conditionally required for the external read or supply internal information processing and determination purposes. Following several pairs of IC card for a simple description ： 1.Contact-type IC card called a C-contact card is used, visible through the electrode contact IC cards interface with external equipment direct contact link Data exchange of IC cards. 2. Non-contact type IC cards so-called non-contact type IC card is through radio waves or electromagnetic induction manner card integration circuit and the data communications equipment external interface IC card. 3.Memory Card Type IC IC card is the main function as a data carrier. IC chips internal circuit can be divided into two functional parts : data storage and dataencryption operation control part. Not all IC cards must also have two major functions. Only data storage functions of IC cards, known as non-encrypted - memory card (Memory Card). With data storage functionality and data encryption and control of the IC card, known as the encryption type memory card, They have temporary or permanent data storage capacity, and its contents for processing or use judgment. Non-encrypted memory card type : use chip is a serial memory chips. To make it Packaging 0. 76mm plastic Khaki, especially manufactured 0. 3mm of thin structure. In addition to the internal chip with the capacity of different data memory circuit, there are corresponding to the address decoding circuits and instructions decoding circuit. Non-memory-based encryption is a passive, generally use synchronous communication mode of IC cards. E
