IC card, also known as "integrated circuit card", smart card, the English name "Integrated Circuit Card" or "Smart card", is the French Roland morono invented in 1974, will have the advantages of integrated circuit card. In 1974, the invention of the French Roland morono, with storage, encryption and data processing capabilities of the integrated circuit chip module encapsulated in the same size as the credit card size of the plastic base, it constitutes the IC card.
IC card has anti-magnetic, anti-static, anti-vandalism and durability, anti-counterfeiting, high security of stored data (encrypted), data storage capacity, application equipment and system network environment, low cost, variety of models, mature technical specifications and other characteristics. It is because the IC card has many incomparable advantages, so in finance, taxation, public security, transportation, post and telecommunications, communications, services, medical care, insurance and other fields have been widely valued and applied.
IC card as a new high-tech products are attracting widespread attention, the key lies in the application of the card, which marks the advent of another new means of information processing. The popularization and application of multi-functional cards in the future will change the way of life of the whole society, and it is the key for mankind to move towards the electronic era in a comprehensive way.
● IC card international standard size ISO9002 standard:
ISO7816 defines the IC card chip midpoint to the left edge of the card distance: 15.06mm, to the upper edge of the distance: 23.89mm (8-pin), 22.62mm (6-pin), width: 85.72-85.74mm, height: 54.03-53.92mm, Thickness: 0.83mm.
●IC Card Classification
By storage capacity: IC card storage capacity is as small as dozens of Bit, as large as dozens of K BYTE
By security level: (1) non-encrypted memory card (2) logical encrypted memory card (3) CPU card
Connecting mode Contact and contactless
By IC chip manufacturers: Germany Siemens, France Gemplus, Atmel, the United States, the Netherlands, Philips, etc.
●Contactless IC card:
Contactless IC card, also known as radio frequency card, is a new technology developed in recent years in the world, in the card close to the reader surface, the card data can be completed read the data in the card, the card can be read by the reader. Can be completed when the card is close to the surface of the read-write data in the card read-write operation, it successfully combined radio frequency identification technology and IC card technology, solved the passive (no power in the card) and contact-free this problem is a major breakthrough in the field of electronic devices, compared with the contact IC card, non-contact IC card has the following advantages:
1. High reliability
Non-contact IC card and read-write between the no No mechanical contact between the contactless IC card and the reader, avoiding all kinds of failures due to contact reading and writing. For example: due to rough insertion of the card, non-card foreign objects inserted, dust or oil resulting in poor contact and other reasons for failure. In addition, non-contact IC card surface without exposed chips, without worrying about falling off, electrostatic breakdown bending, damage and other issues, both to facilitate the printing of the card, but also to improve the possibility of using the card.
2. Convenient and fast operation
Because of the use of radio frequency communication technology, the reader can read and write the card within 10cm, without inserting or removing the card action. Contactless IC card use without direction, the card can be any direction swept across the surface of the reader, read and write time is not greater than 0.1 seconds, greatly improving the speed of each use.
3. Security and conflict prevention
The serial number of the contactless IC card is unique, and the manufacturer has solidified this serial number before the product is shipped out of the factory, which cannot be changed. No two cards in the world will have the same serial number. The contactless IC card and the reader adopt a two-way verification mechanism, i.e. the reader verifies the legitimacy of the card, and the card also verifies the legitimacy of the reader. Contactless IC card in the operation of the reader to be three times before the mutual authentication, and in the communication process all data is encrypted. Each sector of the card has its own operating password and access conditions.
- In addition, there is no mechanical contact between the contactless IC card and the reader, thus avoiding all kinds of failures due to contact reading and writing.
- There is no exposed chip on the surface of the contactless card, so there is no need to worry about the chip falling off, static electricity breakdown, bending damage and other problems.
- The use of non-directional, the card can be swept in any direction across the surface of the reader, to avoid the contact reading and writing in the seat of the mouth tongs due to small and difficult to insert the card difficulties.
- Adopting two-way verification mechanism, the reader verifies the legitimacy of the IC card, and at the same time verifies the legitimacy of the reader, while most ordinary contact IC cards are one-way verification.
Each card has a unique serial number. The serial number is solidified by the manufacturer before the product leaves the factory and cannot be changed, and the serial number is unique.
Commonly used models:
MF1 ICL10, MF1 ICS50, SLE44R35S, meanwhile, our company can also provide customers with un-laminated cards (Inlet) for customers to laminate and produce finished white cards, as well as a variety of contactless and contact IC card readers.
●RF card production process:
Card center punching→chip placement and positioning→antenna winding→butt-welding connecting chips and coils→inspection and testing→printing card fabric→laminating→laminating→inspection and testing→punching→inspection→finished product leaving the factory.
●MI system parameters
MI contactless IC card in line with MIFARE1 international standards, data retention period of 10 years, can be erased and written an unlimited number of times.MI card embedded special chip, ring antenna, encryption control logic circuit and communication logic circuit, the card and the communication between the reader and adopts the standard DES and RES cross algorithms, with a very high degree of intelligence and confidentiality. The communication between the card and reader adopts standard DES and RES cross algorithms, which is highly intelligent and confidential.
●Working Principle
The reader sends a set of fixed-frequency electromagnetic waves to the MI card, and the LC series resonance circuit inside the MI card is excited to generate **** vibration, and sends the electric charge to another capacitor for storage, and when the accumulated electric charge reaches 2V, it can supply power to the card, and transmit the data inside the card or receive the data from the reader.
●Application range
Because contactless IC card has more convenient and quicker characteristics, it can be widely used in electronic wallet, passageway charge control, public transportation automatic ticketing, parking automatic charging, cafeteria food sales, attendance and access control and other occasions.
