Introduction To Smart Card Performance

Edit:Shenzhen Trustags Smartlabel Technology Co.,Ltd  Date:Aug 03, 2017

    Contact Surface: Metal material, generally for copper flakes, integrated circuit input and output terminals connected to the large contact surface, so as to facilitate the operation of the reader, the large contact surface also helps to prolong the service life of the card; contacts generally have 8 (C1 C2 C3 C4 C5 C6 C7 C8, C4 and C8 designed for future retention), but for historical reasons some smart cards are designed as 6 contacts (C1 C2 C3 C5 C6). In addition, C6 original design for the EEPROM power supply, but because later the EEPROM required program voltage (programming voltage) by the chip directly control, so C6 is usually no longer used.     Integrated chip: Usually very thin, within 0.5mm, diameter of about 1/4 cm, generally rounded, square also has, internal chip generally have CPU RAM ROM EPROM.Smart Card
Advantages: 1 Easy to carry: The light card can be conveniently placed in the wallet or in the card bag, can be mailed. 2 Storage Capacity: A card can hold 4-6 megabytes of information. Other portable information media (magnetic cards, IC card, microfiche) are not comparable. 3 Information record of high reliability and high security: because it is a laser drilling record method, so the card is not afraid of any electrical/magnetic interference, there is a strong resistance to water, pollution and the ability to change the temperature. Anyone who tries to change the contents of a card in any way must leave traces. 4 High confidentiality: Canon     Optical card has a unique design of the optical card information confidentiality measures can be made to a card a yards, the code can not be read by conventional methods, more can not be deciphered. 5 is cheap relative to price.Smart Card
    1. Contact IC card: This kind of card is through the IC card reading and writing device contact point and IC card contacts after the data read and write. International standard ISO7816 on the mechanical characteristics of such cards, electrical characteristics, such as strict provisions. 2. Contactless IC card: This type of card and IC card equipment without circuit contact, but through non-contact reading and writing technology for reading and writing (such as light or wireless technology). Embedded chip In addition to CPU, logic unit, storage unit, increased RF transceiver circuit. The International standard ISO10536 series sets forth the requirements for contactless IC cards. This kind of card is commonly used in occasions with frequent usage, relatively little information and high reliability. 3. Dual-Interface card: The Contact IC card and contactless IC card combined into a card, operating independently, but can share CPU and storage space.Smart Card
