Is it possible to read/access the bar-code scanner values using PHP & MySQL?

Question

I am trying to enable a PHP website to recognize barcode input.

I will load a web page in a browser, the focus (cursor) is set to recieve input into the text box.

Answer 1

Most barcode scanners emulate a keyboard.

So as long as the input field has focus when the button is pressed on the scanner, a string with numbers will be written to the field and you can save those.
