Note 1: Is it a domestic card reader or an imported card reader?
The real import access control card reader, the technology is relatively mature, the product repair rate is low, the design is more beautiful and durable. The disadvantage is: the price of the product is expensive, the service does not have a domestic card reader in time, and must use the imported brand induction card. Imported proximity cards are also expensive. Unless the customer specifies the use of an imported brand of card reader, I recommend using a domestic card reader, but must choose a domestic card reader provided by the manufacturer with good quality reputation and service. Domestic card reading. The appearance of the device has also made great progress in the past two years, and it has quickly followed the international popular style. The imported card reader is 6-10 times the price of the domestic card reader, and the price of the imported card is 10-20 times that of the domestic card.
The core chips of domestic card readers and cards are processed by foreign RF chips. The development and production capacity of chips in this field are not available in China. Imported card readers are recommended to use model readers and card readers. The price/performance ratio will be better. Many domestic card readers will affix a brand that does not exist in foreign countries, mark a country with a place of origin, or have a fake certificate of origin. This kind of hanging sheep has a lot of things to buy dog ​​meat. Keep an eye out. Don't spend money, don't buy good products, and get a lot of trouble.
Note 2: Is the ID card reader or IC card reader selected?
ID card reader is a common name for read-only non-contact IC card. IC card reader is a collective name for readable and writable contactless IC card. The performance price ratio and sensing distance of ID card and ID card reader are better than IC. Card and IC card reader. If it is only used for access control and attendance or parking card, it is recommended to use ID card reader and proximity card. If you need to be compatible with non-fixed spending card, you can only use IC card reader and sensor. 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 foreign readers. The molds are common to everyone, and anyone can buy them, so even the same type of card readers may be produced by different manufacturers, services and quality. It is also different. The engineer must have a detailed understanding of the card reader, not to distinguish it from the appearance and price. It is recommended that the engineer buy the card reader from the place where the access controller is purchased. The general access controller manufacturer either Will be supporting sales or production of card readers with similar quality standards. So, how to judge the quality of a card reader? I believe that some domestic card readers use analog circuits instead of RF base station chips in pursuit of low cost. The card reader has a large running current, which is easy to crash or is damaged. It is not recommended. It is recommended that the card reader of the imported RF base station chip be better. Of course, it must be more than half a year from the card reader of the manufacturer you purchased. The time of use and the repair rate as well as the quality standards and word of mouth of the manufacturer are used for judgment.
In addition, the card reader is a long-term use of the device, the circuit design must be protected against the circuit of the anti-crash, this point should also be noted. Note 4: Is the choice of sealing or unsealing card reading It is recommended to use a non-sealed card reader. The reason is: even if the glue is sealed, the buzzer is still exposed, and the water will damage the card reader. The material used for the sealant is resin. Generally, the hand-sealing curing agent is used to mix unevenly. The domestic resin material is cheap but the quality is not good. After long-term use, there will be conductivity, which makes the card reader run chaotic or crash. The imported resin is expensive. Domestic manufacturers are generally unwilling. Adopting, evenly spreading to each card reader requires more than a dozen pieces of cost. In addition, the sealant is not suitable for heat dissipation of the device, and it also affects the performance of the card reader. Therefore, unless special occasions are not necessary, it is necessary to use the sealant. Card reader. For some occasions, some waterproof protection for the card reader can be done.
