Text box with bar code scanner

[latex88]

This question is related to a restaurant POS system design. Is there a way to allow a text field in a form to be filled by a scanner only, unless an event is triggered? Rather than using a magnetic strip ones for gift cards, we're thinking of using the bar code version. However, to prevent employees from fraudulently entering the six digit code, the code must be inputted by a scanner. We do also would like to allow user input with keyboard in case scanner malfunctioning, but would require a "manager" login first.

The bar code scanner I worked with inputs read bar codes into a form text field via sending several individual key strokes. Access / VBA has no way of determining that input is coming from the bar code scanner as opposed to the keyboard.

Thank you for the quick reply. I guess I can just add a security pop-up to ensure the proper authority is inputting the information. So, once the text box has the focus, you just scan the code and the data is filled, or there is an interface/code required?

The scanner I used did not require any additional driver software to attach via USB to a Windows XP computer. "Just plug it in, beep beep beep, and start scanning!"
