1, IC card is an integrated circuit card, also known as smart card, smart card, microcircuit card or microchip card. It embeds the microelectronic chip into the card base conforming to ISO 78 16 standard and makes it into the form of a card. The communication mode between IC card and card reader can be contact or non-contact. According to the communication interface, IC cards are divided into contact IC cards, contactless IC cards and dual-interface cards.

2. The security of 2.IC card is far greater than that of ID card. The card number in the ID card has no permission to read, so it is easy to be copied. The reading and writing of the data recorded in the IC card requires corresponding password authentication, and even each area in the card has different password protection, which fully guarantees the data security. The password for writing data in IC card can be different from the password for reading data, which provides a good hierarchical management method and ensures the security of the system.
