It is a microelectronic chip embedded in the card base in line with ISO 7816 standards, made in the form of a card. IC card reader is the bridge between the IC card and the application system, in the ISO international standard called interface device IFD (Interface Device). IFD CPU through an interface circuit with the IC card connected to the IC card and communication. IC card interface circuit is a crucial part of the IC card reader, according to the actual application system, you can choose the parallel communication, half-duplex serial communication and I2C communication. Depending on the actual application system, you can choose parallel communication, half-duplex communication, serial communication and I2C communication and other different IC card reader/writer chips. Contactless IC card is also known as radio frequency card.
IC card applications
IC card development, research and application is a systematic project involving a variety of technical disciplines in the field of computers, communications, networks, software, card reading and writing equipment, application equipment and other products. Therefore, the global IC card industry in the technology, market and application of the competition in the rapid development of the IC card has been one of the hot products of today's international electronic information industry, in addition to commercial, medical, insurance, transportation, energy, communications, security management, identification and other non-financial fields have been widely used, in the field of financial applications are also increasingly widespread, the impact is very far-reaching. Although IC card entered China relatively late, it has developed rapidly under the strong support of the government. At the end of 1995, the National Golden Card Office organized the preparation of (Golden Card Project Non-Bank Card Application Master Plan) for the overall planning of national IC card application. In order to ensure the healthy development of IC card, under the leadership of the State Council's Golden Card Office, various ministries and commissions such as the Ministry of Information Industry, the Ministry of Public Security, the Ministry of Health, and the State Administration for Industry and Commerce have formulated the development plan of IC card in their industries.
