推荐答案

读卡器将/应该具有唯一的标识符.您需要找出一种从获取的信息到您知道的信息创建映射的方法.

当您检测到更改，启动应用程序或遇到错误时，应枚举设备.您应该记录发现的内容，以帮助您进行分类.

请与提供读卡器的公司联系，并询问如何以编程方式识别设备.我们将无法为您提供更多帮助.

如果您遇到任何具体问题或可以提供更多详细信息，请随时发布另一个问题.

干杯.

Card readers will/should have a unique identifier. You need to figure out a way to create a mapping from the information you''re getting to the information you know.

You should enumerate the devices when you detect a change, when you start your app, or when you get an error. You should log what you find to help you sort it out.

Contact the company that is providing the card readers and ask how to identify the devices programmatically. We''re not going to be able to help you much more than that.

If you run into any specifics or can provide further details feel free to post another question.

Cheers.
