推荐答案

您应该与创建扫描仪的人员交谈-他们应该提供技术支持并将比我们更了解他们的产品.如果他们没有，请找其他供应商并要求您退款！

You should talk to the people who created the scanner - they should provide technical support and will know more about their product than we will. If they don''t, then find another supplier and demand your money back!

设备制造商可能会提供一个API来访问扫描信息.请检查文档.

在扫描仪的外壳中，有红色激光，它被转向镜反射，从而产生红色激光线的错觉.当此线"指向条形码时，用黑色打印的区域反射的光线与未使用白色区域的反射方式不同.然后，条形码阅读器再次检测到该反射光.这就是条形码扫描仪读取代码的方式.

In the housing of the scanner, there is a red laser, that is reflected by a turning mirror and thus creates the illusion of a red laser line. When this "line" is pointed on a barcode, the areas printed in black colour reflect the light differently than the left out white areas. This reflected light is then detected by the barcode-reader again. That is how the barcode-scanner reads the codes.
