推荐答案

不知道条形码扫描仪是什么的答案是一种猜测，但我的猜测是，用于访问条形码扫描仪的任何API都会因型号/制造商/接口或扫描仪ID应可从制造商提供的API中获得.

因此，实际上是通过API接口查看哪些信息可用，以确定哪个扫描程序提供了该信息.

Without knowing what the barcode scanners are any answer will be a guess but my guess is that any API to access a barcode scanner will differ based on model/maker/interface or the scanner ID should be available from the API supplied by the manufacturer.

So really it is a matter of looking at what information is available via the API interface to determine which scanner provided the information.
