I have a client that is currently using a Snapshell R2 scanner to scan ID Badges.  The quality has degraded to a point they are looking for alternatives.  I know that PhotoDocs is an option for this, but would like to be able to present other options.  After a quick internet search, I found that Ambir has a several that include a Twain driver: http://www.ambir.com/Ambir-Card-Scanners.  Does anyone have a recommendation for an ID card scanner?
