What about the products of Shenzhen Huaming Innovation Technology Co., Ltd.?

This company is still good. I don't know what product to ask. Our school bought a canteen charging system before. We use a company in Guangzhou, and the quality is average. We didn't pay attention to it after sale. Later, I changed the innovative products of Shenzhen Huaming, and all of them were replaced at one time, including computers and cards. We deducted money from their canteen to buy more than 20 machines and more than 3,000 cards, which have been used for 7 months. There is no problem at present and there is no maintenance machine. As for the service, it should be said that it is better. An old computer that we used to manage computers before, the computer system was broken. Later, we bought a new computer and called them at 6 pm on Sunday to help them change the system (we were in Guangzhou). This is none of their company's business. Their business people will come to help us change the system with technology in the evening. Because the computer system is not compatible with WIN 10, and it is a new CPU, it took a whole night to install WIN7 (mainly because our computer is not connected to the Internet, otherwise it will be installed soon). Generally speaking, the quality is good, the service is good and the price is more expensive than others. In the past, I wanted to be cheap, but I still had to change products. The cost was relatively high, and overall, the cost performance was still relatively high! I hope I can help you, and I hope to adopt it!
