br 一 Product Information
br rr br br br The card is a contactless card, also known as a radio frequency card. It consists of a chip 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 problem of no power supply and contact-free in passive cards. It is a major breakthrough in the field of electronic devices. The card is usually close to the surface of the reader at a certain distance, and the data reading and writing operations are completed through the transmission of radio waves.
br rr br br brRead and write operations are completed through radio waves between the contactless card and the card reader. Communication between the two is frequent. The non-contact card itself is a passive card. When the reader/writer reads and writes the card, the signal sent by the reader/writer is superposed by two parts. One part is the power signal. After the signal is received by the card, it is combined with its own/generated signal. An instant of energy is supplied to the chip to work. The other part is the command and data signals, which instruct the chip to complete the reading, modification and storage of data, etc., and return signals to the reader and 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 communication interfaces, printing ports, / ports, etc., so that it can be used in different fields.
br rr br br br The internal partition of the contactless smart card
br rr br br br The internal partition of the contactless smart card is divided into two parts: system area and user area
br rr br br br The system area consists of the card Used by manufacturers and system developers and card issuers.
br rr br br br The user area is used to store relevant data information of the cardholder.
br rr br br br Compared with contact cards, contactless cards have the following advantages
br rr br br br ⑴ High reliability There is no mechanical contact between the contactless card and the reader. Various failures caused by contact reading and writing are avoided. 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 are no exposed chips 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.
br rr br br br ⑵Easy to operate
br rr br br br Due to non-contact communication, the reader can operate the card within the range, so there is no need to insert and 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.
br rr br br br ⑶Anti-collision
br rr br br br There is a fast anti-collision mechanism in contactless cards, which can prevent data interference between cards. Therefore, the reader can process multiple cards at the same time. A contactless card. This improves the parallelism of the application and virtually increases the system working speed.
br rr br br br ⑷ Can be suitable for a variety of applications
br rr br br br The serial number of the contactless card is unique. The manufacturer has solidified this serial number before the product leaves the factory. It cannot be Change again. 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.
br rr br br br ⑸Good encryption performance
br rr br br br The contactless card consists of a chip, an 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.
