Contact IC card description:
 Contact IC card is integrated circuit card (Integrated Circuit Card) is short, is a mosaic integrated circuit chip plastic cards, its shape and size are in accordance 

with international standards (ISO / IEC 7816, GB / T16649). Chip generally uses non-volatile memory (ROM, EEPROM), protection logic, and even with a microprocessor 

CPU. Read and write through the contacts of the device contacts with the chip after the data read and write. The integrated circuit chip encapsulated in the card can 

record and refresh the stored contents. In use, through the tangible electrode electric shock to the card's integrated circuit and external interface devices directly 

contact the connection, the data exchange.
Contact IC card features
  ⑴ large storage capacity: its internal RAM, ROM, EEPROM, and other memory, storage capacity can be megabytes, can store text, sound, graphics, images, and other 

information.
  ⑵ small size, light weight, anti-interference ability, easy to carry, easy to use.
  ⑶ high security: IC card hardware and software from several aspects, such as the implementation of its security strategy, you can control the card access to 

different regions of the characteristics. Encryption IC card itself has a security password, if you try to illegally access the data on the card self-destruction, can 

not be read and write.
  ⑷ less demanding on the network: IC card security and reliability in the application environment in the computer network real-time, lower sensitivity requirements, 

very consistent with the current national conditions, is conducive to the network quality is not high in the environment.
Mainly used in stored value cards, utilities, coal, three table industry utilities, hotel door cards, cable TV cards, Internet cafes management card, tax cards.
