How do I use a barcode font in a PDF document?

I have made a PDF template from Adobe InDesign and use Adobe Acrobat 11 (Standard) to insert fields into the PDF document.

However I have trouble getting it to work.

I use the "BC C39 3 to 1 HD Wide" font in the text field. OK

I have tried to use a script (found in this forum) to insert a * both in front and after the number/text:

var s = getField("text1").valueAsString;

event.value = s ? "*" + s + "*" : "";

The resulting field as a barcode is ment to be entered via a bar code scanner. OK

But when I try to scan the new created barcode nothing is written at the cursor.

I put the cursor in Excel or text editor.

Is there some extra functionality in Acrobat Pro 11 for this purpose. Or another version of Acrobat.
