Smart cards are widely used worldwide in industries that support access, identity, payment and other applications. This article is some of the areas and information I found about smart card applications. I hope you find it useful. If you have any needs or questions, you can contact us directly. Our professional staff is always available to answer your questions.
This passage is going to talk about the followings of smart cards:
1) Application areas of smart cards
2) Components of smart cards
3) Choose our smart cards
Here are some applications for smart cards.
Internet of Things (IoT).
Hardware substrate: mostly PVC material, also have plastic or paper system
Contact surface: metal, generally copper sheet, the input and output of the integrated circuit is connected to a large contact surface, which facilitates the operation of the reader, and the large contact surface also helps to extend the service life of the card; there are generally eight contacts (C1 C2 C3 C4 C5 C6 C7 C8, C4 and C8 are designed for future retention), but for historical reasons some smart cards are designed with six contacts (C1 C2 C3 C5 C6 C7). However, for historical reasons some smart cards are designed with six contacts (C1 C2 C3 C5 C6 C7). In addition, C6 was originally designed to supply power to the EEPROM, but since the EEPROM's required programming voltage is controlled directly from within the chip, C6 is usually no longer used.
Integrated chip: usually very thin, within 0.5mm, diameter of about 1/4 cm, generally into a circle, square also have, internal chip generally have CPU RAM ROM EPROM.
Software has a card operating system COS (Chip Operating System). The card operating system is used to respond to the instructions sent by external devices to the card, such as verify the calculation, read and write data, read the card number, write the key, lock the data area, illegal operation automatically destroy the card related settings, verify the card reader privileges and so on.
The data stored in the card, generally stored data are: algorithm used to verify the reader's authority, the verified key, card number, data area (for example, bus card can save the balance, card date, parking lot card can save the entry time, dining card can save the remaining amount, user information).
In 2011, China's IC cards achieved a record sales revenue of about 9 billion yuan, an increase of 11.1% over 2010, and the number of cards sold reached 2.43 billion, an increase of 13.6% over the previous year. It is expected that China's IC card industry is expected to grow at about 14% in the next three years. China is a country with rich experience in smart card production.
Hecere was founded in 2008. At beginning, our main business was smart cards, such as magnetic stripe cord, contact chip cord and RFID card.
In 2015, our company started to manufacture BFID label We gradually expanded our business rom smart cards to RFID labels.
In 2017. we integrated resources of RFID wristbands RFID keyfobs RFID anti-metol tag RFID reader RFID lock and so on, which bunt a powerful supply BEID products cham to meet our client's various requirements.
