1, there are two in Beijing, Beijing Bojiete Information Technology Development Center and Beijing Aijia Xinye Technology Development Co., Ltd.
Berger's machine brand is not well-known, but almost one-third of schools in Beijing use Berger's machines with good quality and good after-sales service. Ai Jia company borrows the brand of Ziguang, the quality is acceptable, but the after-sales service is poor.
2. There are many manufacturers in Hebei, mostly concentrated in Hengshui, including Hengshui Nanhao, Hengshui Aoke and Hengshui Li Sheng. Basically, they are township enterprises, and the prices are relatively cheap. I don't believe you can find Nanhao everywhere on the Internet, and there are many online promotions.
There is a Huai Yu company in Nanjing, whose influence is mainly in Jiangsu, and its national sales volume is not very large.
4. Guangdong Yishibao is engaged in lottery entry, and its customers are not concentrated in schools and education fields, so the software is not applicable.
5. Shanghai Tianxin has withdrawn from production and no longer focuses on optical tag readers.
6. Shandong Shanda Ou Ma Machine is also good. The original market share was relatively high. In recent years, it may have disappeared due to internal separation and other reasons.
The above opinions are for your reference.
