The non-contact IC card (inductive IC card) reader for door prohibition is an important part of the access control system. It is the key device for the signal input of the access control system and is related to the stability of the entire access control system. The card reader emits electromagnetic waves at a fixed frequency. The frequency is generally 13.56MHZ. When the proximity card enters the electromagnetic wave radiation range of the reader, it will trigger the coil on the proximity card to generate current and trigger the antenna on the proximity card to read the card. The card reader transmits a signal with card information. The card reader converts the level signal into a digital serial number and transmits it to the local controller. The local controller uploads the information to the upper controller, and finally uploads it to the access control server. The server compares the card number with the information in the database to obtain all the card information.
The door disabled IC card (inductive IC card) reader is an important part of the access control system and the key device for the signal input of the access control system. If the access control system is compared to a person, the card reader is like a human eye. It is related to the stability of the entire access control system. If an access control system controller and electric lock are both good, if the quality of the card reader is defective, it will also cause the door not to be opened, which will affect the acceptance and use of the project.

Card reader classification:

The card reader is divided into contact card reader and non-contact card reader from the card reading distance.
The card reader is divided into single interface card reader, dual interface card reader and multi-card socket contact reader from the readable card interface.
From the interface point of view, the card readers mainly include: parallel port card reader, serial port card reader, USB card reader, PCMICA card reader and IEEE 1394 card reader.
The card reader can be divided into two types from the card reading protocol, one is the 485 card reader and the other is the Wiegand card reader. Wiegand 26 and 34 agreements, these two agreements are conventional agreements.
The card reader can be divided into IC card reader and ID card reader from the card reader type. The IC card reader is a non-contact IC card reading and writing device, which realizes the connection with the PC through the USB interface, and a single 5V Power supply or keyboard port to get electricity, it supports access to all functions of the radio frequency card. This series of equipment is used in card issuing systems for access control, attendance, conference sign-in, highways, tourism, parking lots, public transportation, shopping mall consumption, membership systems, and various application systems.
The ID card reader is used to read ID cards. The reader supports plug-and-play. It can be plugged and inserted at will during use. No external power supply is required. Users do not need to load any drivers. Windows systems directly treat them as HID devices. keyboard. After the computer USB port is connected to the card reader, the card reader starts self-checking and initialization with a beep, and then the initialization is successful with a beep, and it enters the state of waiting for card swiping.
ID card reader, information query, Internet cafe registration, book borrowing, conference sign-in, access control and other occasions.

Note 1: Should I choose a domestic card reader or an imported card reader?
The real imported card reader, the technology is relatively mature, the repair rate of the product is low, and the appearance design is more beautiful and attractive. The disadvantages are: the product is expensive, the service is not as timely as the domestic card reader, and the imported proximity card of the supporting brand must be used. Proximity cards are also more expensive. Unless the customer specifies the use of an imported brand reader, the author recommends using a domestic card reader, but you must choose a card reader provided by a manufacturer with good domestic quality, reputation and service. Domestic card reader The appearance of the card has also made great progress in the past two years, and it is about to keep up with the internationally popular styles. Imported card readers are 6-10 times the price of domestic card readers, and the price of imported cards is 10-20 times that of domestic cards. Domestically produced The core chips of card readers and cards are all processed with foreign radio frequency chips. China does not have the development and production capabilities of chips in this field. It is recommended to use model readers and card readers for imported card readers. Relatively speaking The price/performance ratio will be better. Many domestic card readers just affix a brand that does not exist in foreign countries, mark a country of origin, or have a fake certificate of origin. There are many things to buy dog meat with sheep's head, and the engineering company should pay attention to it. Don't spend wronged money and have not bought a good product, causing a lot of trouble.
Note 2: Should I choose an ID card reader or an IC card reader?
ID card reader is a common name for read-only non-contact IC cards, and IC card reader is a general term for readable and writable non-contact IC cards. The performance-price ratio and sensing distance of ID cards and ID card readers are better than IC Card and IC card reader. If it is only used for access control and time attendance or parking lot card, it is recommended to use ID card reader and proximity card. If you need to be compatible with non-fixed consumption card, you can only use IC card reader and induction Card. ID card market is more popular and cost-effective is EM card.
Note 3: Do not judge the quality of domestic card readers from the appearance alone.
Most domestic card readers use public molds, or copy the appearance of foreign readers. The mold is universal, anyone can buy the shell, so even if the reader of the same appearance may be produced by different manufacturers, the service and quality It is also different. The project company must have a detailed understanding of the card reader, not just from the appearance and price to distinguish it. It is recommended that the project company buy the card reader from the place where the access control controller is purchased, and the general access control controller manufacturer either Will support the sales or production of card readers with similar quality standards. So, how to judge the quality of a card reader? In my opinion, some domestic card readers use analog circuits to replace RF base station chips in pursuit of low production costs. The card reader has a large operating current and is easy to crash or be damaged. It is not recommended. It is recommended to use a card reader with an imported RF base station chip. Of course, you must also purchase a card reader from the manufacturer you previously purchased for more than half a year Use time and repair rate as well as the manufacturer's quality standards and reputation to make judgments. In addition, the card reader is a long-term use device, and the circuit design must be protected by an anti-crash circuit. This point should also be paid attention to. .
Note 4: Should I choose a sealed or unsealed card reader?

It is recommended to use an unsealed card reader. The reason is: even if the glue is sealed, the buzzer is still exposed, and water entering here will damage the card reader. The material used in the sealing glue is resin, which is generally used in China The manual sealant curing agent is used to mix unevenly. Domestic resin materials are cheap but of poor quality. They will have conductivity after long-term use, which will make the card reader run chaotic or crash. Imported resins are expensive. Domestic manufacturers are generally unwilling to use them. It costs more than a dozen yuan per card reader. In addition, the sealant is not suitable for the heat dissipation of the device, and it also has an impact on the performance of the card reader. Therefore, unless there is a special occasion, it is generally not necessary to use the sealant to read Card reader. For special occasions, some waterproof protection for the card reader is enough.

The working principle of the card reader:

The card reader emits electromagnetic waves at a fixed frequency. The frequency is generally 13.56MHZ. When the proximity card enters the electromagnetic wave radiation range of the reader, it will trigger the coil on the proximity card to generate current and trigger the antenna on the proximity card to read the card. The card reader transmits a signal with card information. The card reader converts the level signal into a digital serial number and transmits it to the local controller. The local controller uploads the information to the upper controller, and finally uploads it to the access control server. The server compares the card number with the information in the database to obtain all the card information.
