Based on the structure can be divided into: memory card, logic encryption card, cpu card, super smart card. According to the interface can be divided into: contact IC card , contactless IC card, dual interface card. Specifically you can look at the logo on the card.
Because the IC card has a small size and easy to carry, large storage capacity, high reliability, long service life, confidentiality and high security, the concept of IC card was put forward in the early 1970s.
France's Boolean company first created IC card products in 1976, and this technology is used in finance, transportation, medical care, identification and other industries, which combines microelectronics and computer technology to improve the modernization of people's work and life.
Product Principle:
IC card is an integrated circuit card, IC card chip has the ability to write data and store data, and can determine the content of the IC card memory. In the card encapsulated with a chip that meets ISO standards, there are 6 to 8 contacts and external devices to communicate, in the IC card can have color patterns and descriptive text according to ISO standards.
IC card part of the contacts and its definition: VCC: IC card operating power; GND: ground; VPP: memory programming power; CLK: timing and synchronization of the relevant signals; I / O: card serial data input and output; RST: reset signal. When the IC card is inserted into the IC card reader, each contact corresponds to turn on, the IC card on the ultra-large-scale integrated circuit will begin to work.
