How to distinguish the quality of the access control card reader? Because the price of card readers on the market is very high and some are very low.

Yes, there is a big gap in the price of many access card readers in China at present. Many domestic access control card readers have many quality problems, which makes it difficult to carry out maintenance work in many projects. In terms of the choice of access control card readers, I personally recommend using some well-known brand products, although the price of well-known products is high, the quality is guaranteed, it will not cause problems for users, and it also reduces the maintenance work of our engineers.
