What Is Integrated Circuit Card

Integrated circuit card, also known as IC card, is composed of one or more integrated circuits embedded in a plastic card of the same size as an ordinary credit card. Integrated circuit chips can be memory or processor. IC cards with memory are also called memory cards or memory cards, and IC cards with microprocessors are also called smart cards or smart cards. Memory cards can store a lot of information; Smart cards not only have memory ability, but also have the function of processing information.

The Development OF IC Card

The IC card was invented by a French journalist in 1974. Because of its small and exquisite, easy to carry, large storage capacity, good confidentiality, long service life and low manufacturing cost, it is increasingly favored by people. Today, it has been widely used in financial circulation, shopping prepaid, identity authentication, data records and other aspects.

For example, IC cards can be very convenient to pay a variety of petty expenses, such as saving car fees, telephone fees, subway fares, canteen meals, highway fees, shopping Tours, trade services, etc.

IC card can also record personal information, such as my physical characteristics, work resume, medical history, every drug and other information, in order to meet the needs of social activities, personal financial account, tax storage, reward and punishment records, meeting minutes, etc., can also be used with the support of the network management system, at any time to call out the relevant information.

In the field of communications, IC cards can be used to hang up public phones, pay phone bills, mobile communications and cable television and other new services that require identification of personal codes to be allowed to use. IC card public telephone is a widely used field of IC card at present. Because the IC card phone reader does not have any mechanical action, and has IC card security and anti-counterfeiting functions, it is more reliable, safe, flexible and management than the magnetic card phone.
IC cards in rapid development, there are 300 million, and an annual growth rate of 40% is widely used in various fields, become an important indicator of the level of economic development of a country. The number of cards issued in Europe has reached 114 million; France ranks first in the world in both card issuance and card reading equipment.

The United States and Japan are the early countries to implement credit cards, but they mainly apply IC cards in areas with high security requirements. For example, the identity card of the United States military has all used IC card identification system; The student card of Singapore university students uses IC card, which can be used as identity proof, but also to record students' scores, books and sports goods borrowed, attendance, and can also be used as a meal card and small amount of time on campus.

Features OF IC Card

IC card features 1IC carrier board. High reliability IC card is by reading, writing device contact head and integrated circuit contact point on the card stop information reading and writing, the reader does not have any moving parts, simple and reliable, IC card has anti-interference ability strong, anti-magnetic and anti-static. And other characteristics. 2. IC card from consumption to put into use in the whole process and the whole life cycle can stop the harsh processing, so the safety is good.

IC card uses the information verification code (MAC), in the identification of the card, by the card number, expiration date and other important data and a key according to the inevitable algorithm to stop calculation verification IC carrier. IC card can provide key personal identification (PIN) code, when the user uses, after entering the password, and the PIN code to stop the force, to avoid illegal users. 3. The sensitive IC card itself can stop security authentication, operation permission authentication, and can store the latest information about transaction processing, can stop offline operation, and simplify collection requirements.

IC card can be used for multiple ic carrier board. IC cards can provide convenience for users: for example, for users to modify the PIN code, personal data materials, consumption rights, and query balances. Those functions show the sensitivity of the IC card. Third, the application of IC card in the telecommunications industry 1. Public IC card is the fastest IC card application, the use of countries and regions most of a kind of IC card.

Because the coin operator has to clean the money box and dispose of a large number of coins, the work is cumbersome, and the criminals will steal the coins and even destroy the ic carrier plate of the blower. Because the safety of the magnetic card phone is low, the magnetic card is easy to be copied and copied, and the phone is more faulty than the force. IC card phone safe and reliable, easy to operate, telecom operators are willing to launch, a wide range of users like to use. Therefore, once IC card phone came out and developed quickly, it gradually replaced coin-operated phone and magnetic card phone. The change in our country is especially great. Now there are less and less coin-operated phone and magnetic card phone in the streets.

2ic carrier board. The user identification form of smart card (SIM card) because the SIM card is small, low power consumption, high safety, and can be proved by the cardholder itself, it has become a user card in the GSM digital mobile phone system. When the user makes a phone call or calls a phone call from a mobile phone with a SIM card removed, the phone charge is recorded in the storage area of the SIM card according to a unique number. Mobile phone users who accept prepaid storage in the SIM card can also deduct the cost of each call.

The SIM card can also provide mobile phone users with various functions such as call limitation, incoming call number display, call number accumulation display and short dynamic display. SIM card plays an important role in mobile phone, through user proof and data encryption, SIM card effectively avoids all kinds of fraud, its PIN code can also protect users from being stolen, strengthen the communication of individualism.

The scale of the SIM card can make each manufacturer's equipment compatible with each other like the GSM digital mobile phone system, so that the user has a SIM card in hand and can plug it into the ic carrier of any manufacturer's mobile phone. 3. At present, all kinds of financial cards issued by various banks and post offices belong to financial cash IC cards, financial cards can be deposited and withdrawn in ATMs (active teller machines), and can also be used in shopping malls and other places.
