The card is a contactless card, also known as a radio frequency card. It is composed of a chip and an induction antenna and is packaged in a standard card without 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 to end the problem of passive (no power supply in the card) and contact-free. It is a major breakthrough in the field of electronic devices. The card completes data reading and writing operations through the transmission of radio waves at a certain distance (usually) close to the surface of the reader.
.The reading and writing operations are completed through radio waves between the contactless card and the card reader. The communication frequency between the two is... The non-contact card itself is a passive card. When the reader reads and writes the card, the signal sent by the reader is composed of two superposed parts: one part is the power signal. This signal is received by the card and combined with its own energy to generate an instantaneous energy. to supply chip work. The other part is the instruction and data signals that direct the chip to complete the reading, modification, storage, etc. of data and return signals to the reader to complete a read and write operation. The reader/writer is generally composed of a microcontroller-specific intelligent module and an antenna, and is equipped with a communication interface printing port/port, etc., so that it can be used in different fields.
.Contactless smart card internal partition
Contactless smart card is divided into two parts: system area (D) user area (D)
System area: divided by card manufacturers and system developers and card issuers.
User area: used to store cardholder related data information.
. Compared with contact cards, contactless cards have the following advantages:
⑴ High reliability. There is no mechanical contact between the contactless card and the reader, which avoids various problems caused by contact reading and writing. kind of malfunction. For example: the fault is caused by poor contact due to rough insertion of the card and the insertion of non-card foreign objects such as 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 problems such as 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
Since the non-contact communication reader can operate the card within the range, it is very convenient for users to use without having to insert and remove the card. There is no directionality when using contactless cards. The card can sweep across the surface of the reader in any direction to complete the operation, which greatly improves the speed of each use.
⑶Anti-collision
There is a fast anti-collision mechanism in contactless cards to prevent data interference between cards, so the reader can process multiple contactless cards at the same time. This improves the parallelism of the application and virtually increases the speed of the system.
⑷ Can be suitable for a variety of applications
The serial number of the contactless card is unique to the manufacturer. This serial number has been solidified 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 the card also verifies the legitimacy of the reader/writer.
⑸ Good encryption performance
Contactless cards are composed of chip induction antennas and are completely sealed in a standard card with no exposed parts. The reading and writing process of contactless cards is usually completed by radio waves between the contactless card and the reader.
