Note 1: Is it a domestic card reader or an imported card reader?
The real imported card reader, the technology is relatively mature, the product repair rate is low, the design is more beautiful and durable. The disadvantages are: the product is expensive, the service does not have domestic card reader in time, and must use the imported brand of induction card, import The proximity card is also expensive. Unless the customer specifies the use of an imported brand of card reader, I recommend using a domestic card reader, but be sure to choose a domestic card reader with good quality reputation and good service. Domestic card reader The appearance of the two years has also made great progress, and quickly catch up with the international popular style. 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. The core chips of 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 are free to stick to a brand that does not exist in foreign countries, mark a country of origin, or have a fake certificate of origin.
Note 2: Is the ID card reader or IC card reader selected?
The ID card reader is a common name for a read-only contactless IC card. The IC card reader is a collective name for a readable and writable contactless IC card. The performance price ratio and sensing distance of the ID card and the ID card reader are better than those of the 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 popular and cost-effective is EM card.
Note 3: Do not judge the quality of domestic card readers from the appearance.
Domestic card readers mostly use public molds, or copy the appearance of foreign card readers. Molds are common to everyone, and anyone can buy the case, so even the same type of card reader may be produced by different manufacturers, service 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. Use time and repair rate and the manufacturer's quality standards and word of mouth to judge. In addition, the card reader is a long-term use of equipment, circuit In the design, there must be a circuit to protect against the crash, which is also to be noted.
Note 4: Is it a sealed or unsealed card reader?
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. The use of manual sealant curing agent is unevenly mixed. Domestic resin materials are cheap but of poor quality. After long-term use, there will be conductivity, which makes the reader operate chaotic or crash. Imported resin is expensive. Domestic manufacturers are generally reluctant to adopt. It costs more than a dozen pieces for each card reader. 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 holder. It is ok to protect the card reader from some special occasions.
