如何使用外部文本输入源（例如扫描程序）输入数据而不使用HTML输入字段？

Question

I have attached my usb scanner to the pc. it works well with a normal input field. But i dont want to show the field box. I only want to read the Data through scanning.

I tried hidding the input field by using input type="hidden" . that hides the field but data doesnt pass. I tried display:none; same as before. And Finally i tried vanishing the field's border/outline But it was useless.

Just Figured out that setting the z-index: -1 does the trick. If there's a better option let me know
