Hubei Wuhan Shenrui Intelligent Technology Co., Ltd. provides bulk supply of non-contact IC cards, induction IC cards, and RF IC cards at manufacturer's discounted prices.

Non contact IC card, also known as induction IC card or RF IC card, is composed of an IC chip and an induction antenna, packaged in a standard PVC card, with no exposed parts of the chip and antenna. It is a new technology developed in recent years in the world that successfully combines radio frequency identification technology with IC card technology, ending the problem of passive (no power supply in the card) and contactless. It is a major breakthrough in the field of electronic devices The card approaches the surface of the reader/writer within a certain distance range (usually 5-10mm) and completes data reading and writing operations through the transmission of radio waves.
1. Non contact IC cards and card readers complete reading and writing operations through radio waves. The communication frequency between the two is usually 13.56MHz, and some card types also operate at other frequencies. The non-contact IC card itself is a passive card. When the reader/writer performs read and write operations on the card, the signal emitted by the reader/writer is composed of two parts: one is the power signal, which is received by the card and generates an instantaneous energy with its own L/C to supply the chip for operation. The other part is instructions and data signals, which command the chip to complete data reading, modification, storage, etc., and return signals to the reader/writer to complete a read/write operation. Readers and writers are generally composed of microcontrollers, dedicated intelligent modules, and antennas, and are equipped with communication interfaces with PCs, printing ports, I/O ports, etc., for application in different fields.
2. Non contact smart card internal partitioning
The non-contact smart card is divided into two parts: the system area (CDF) and the user area (ADF)
System area: Used by card manufacturers, system developers, and issuing institutions.
User area: used to store relevant data information of cardholders.
Compared with contact IC cards, non-contact cards have the following advantages:
⑴. High reliability: The non-contact IC card has no mechanical contact with the reader/writer, avoiding various faults caused by contact reading and writing For example:
Malfunctions caused by poor contact due to rough insertion of non card foreign objects such as dust or oil In addition, there are no exposed chips on the surface of non-contact cards, so there is no need to worry about chip detachment, electrostatic breakdown, bending or damage. This not only facilitates card printing but also improves the reliability of card use
⑵ Easy to operate
Due to the fact that non-contact communication readers can operate cards within a range of 10CM, there is no need to insert or unplug cards, which is very convenient for users to use When using a non-contact card, there is no directionality. The card can skim over the surface of the reader in any direction to complete the operation, which greatly improves the speed of each use
⑶ Conflict prevention
There is a fast anti-collision mechanism in contactless cards to prevent data interference between cards, so the reader/writer can 'simultaneously' process multiple contactless IC cards This improves the parallelism of the application and invisibly increases the system's working speed
⑷ Can be suitable for various applications
The serial number of the non-contact card is the only one that the manufacturer has solidified before the product leaves the factory and cannot be changed again The non-contact card and the reader/writer adopt a bidirectional verification mechanism, where the reader/writer verifies the legitimacy of the IC card and the IC card also verifies the legitimacy of the reader/writer
Non contact cards need to undergo three mutual authentications with the reader/writer before processing, and all data is encrypted during communication In addition, each sector in the card has its own operation password and access conditions
The memory structure characteristics of contact cards enable them to be used for multiple purposes in different systems. Users can set different passwords and access conditions according to different applications
⑸ Good encryption performance
A non-contact IC card consists of an IC chip, an induction antenna, and is completely sealed in a standard PVC card with no exposed parts. The reading and writing process of non-contact IC cards is usually completed through radio waves between the non-contact IC card and the reader/writer.
The non-contact IC card itself is a passive body. When the reader/writer performs read and write operations on the card, the signal emitted by the reader/writer is composed of two parts: one is the power signal, which is received by the card and resonates with its own L/C, generating an instantaneous energy to supply the chip for operation. The other part is to combine data signals to command the chip to complete data, modification, storage, etc., and return it to the reader/writer. The reading and writing system formed by non-contact IC cards has greatly simplified both hardware structure and operation process. At the same time, with the help of advanced management software and offline operation methods, the data reading and writing process is made simpler.
High temperature resistant induction card
To meet practical application needs, we continuously develop high-performance induction cards that are suitable for special application environments. In terms of high temperature resistance, bending resistance, and the use of environmentally friendly materials, we use imported high-temperature resistant materials composite, which have superior characteristics of high temperature resistance and bending resistance. They are not easily deformed under high temperature exposure on the front of the car, and do not affect their functional characteristics. Combined with our induction card reader/writer, they are widely used in highway toll collection and community management.
