如何在不打开表单的情况下将条形码阅读器发送的值输入表单的文本字段？

Question

I have developed a very basic attendance taking system using barcode reader with PHP-MySQL. I have a form and there I have only one text input to receive value from barcode. After the form is submitted (my barcode reader automatically triggers submit) my script does some processing and then inserts values into my mysql database. This is working fine, but the problem is every time when someone gives attendance the operator needs to stop other works and open the form and keep it that way until the attendance giving is finished.

Now, is there any way by which I can create the the system like the operator doesn't have to open the form or pay any attention to it every time someone gives attendance? For your information I am running the application on local host.

Thanks in Advance :)

Hope that I understood you right. Correct me if not.

When your barcode reader-software is able to do so, or if you can create a small program for the task:
The barcode reader software could run the default webbrowser with the forms url. Let the form url be http://localhost/form.php and use the GET method. So your software could send the data to the php script by querying http://localhost/form.php?data=12345 .
