/ / / / / The card is a contactless
card, also known as a radio frequency card. It consists of a
chip and an induction antenna, and is packaged in a standard
card. The chip and antenna do not have any exposed parts. It is a new technology developed in the world in recent years
It successfully combines radio frequency identification technology and
card technology
Ending the passive
(no power supply in the card
) and contact-free
This is a major breakthrough in the field of electronic devices
The card is close to the surface of the reader at a certain distance (usually

). Data reading and writing operations are completed through the transmission of radio waves.
Contactless
Reading and writing operations are completed through radio waves between the card and the card reader. The communication frequency between the two is
. Non-contact
The card itself is a passive card. When the reader/writer performs read and write operations on the card, the signal sent by the reader/writer is superimposed on two parts. One part is the power signal. After the signal is received by the card, it is combined with the signal. Its own
/ generates an instant energy to supply the chip to work. The other part is the command and data signals, which instruct the chip to complete data reading, modification, storage, etc., and return signals to the reader/writer to complete a read and write operation. The reader/writer is generally composed of a microcontroller, a dedicated intelligent module and an antenna, and is equipped with a communication interface, a printing port, a
/ port, etc., so that it can be used in different fields.
Internal partition of contactless smart card
Contactless smart card is divided into two parts: system area (
) user area (
)
The system area is composed of the card manufacturer and Used by system developers and card issuers.
The user area is used to store relevant data information of the cardholder.
Compared with contact
cards
Contactless cards have the following advantages
⑴ High reliability Contactless
There is no mechanical contact between the card and the reader , avoiding various failures caused by contact reading and writing. For example, the failure may be caused by rough insertion of the card, insertion of foreign objects other than the card, or poor contact caused by dust or oil. In addition, there is no exposed chip on the surface of the contactless card, so there is no need to worry about chip falling off, electrostatic breakdown, bending damage, etc. It not only facilitates card printing, but also improves the reliability of the card.
⑵Easy to operate
Due to non-contact communication, the reader can operate the card within the
range, so there is no need to insert or remove the card, which is very convenient for users to use. Contactless cards have no directionality when used. The card can pass over the surface of the reader in any direction to complete the operation, which greatly improves the speed of each use.
⑶ Anti-collision
The contactless card has a fast anti-collision mechanism
which can prevent data interference between cards. Therefore, the reader can process multiple contactless cards at the same time
card. This improves the parallelism of the application and virtually increases the system working speed.
⑷ Can be suitable for a variety of applications
The serial number of the contactless card is unique. The manufacturer has solidified the serial number before the product leaves the factory
and cannot be changed. A two-way verification mechanism is used between the contactless card and the reader/writer, that is, the reader/writer verifies the legitimacy of the card, and at the same time the card also verifies the legitimacy of the reader/writer.
⑸Good encryption performance
Contactless
The card is composed of
chip, induction antenna, and is completely sealed in a standard
card with no exposed parts. The reading and writing process of a contactless
card is usually completed by radio waves between the contactless
card and the reader.
