Some background information first: Comic book barcodes involve an additional 5 characters in the UPC which help to identify the issue, cover, and printing of a comic. ISBNs for graphic novels also include 5 additional numbers which help to identify pricing changes.
The Comet Standard has a very good summary of the different UPC flavurs of comics - see: Comic Book Barcodes Explained.
Manage Comics is always looking for more scanners, so if you have a good scanner that works well with comics, please reach out to us and let us know the details to make it work and we will include it here.

They are inexpensive and have good support.
