barcode scanner

[Frank D. Engel, Jr.]

This is not normally a problem.  One would typically want the ability 
to key in the same data being scanned in the instance that the scanner 
fails to read the barcode (as sometimes can happen with an inaccessible 
or poorly conditioned barcode), so this overlap would actually make 
life easier.
