I think you could add a spot for each card in tthe inventory so the backs of the cards can be scanned in as well. Treat it just like you would for the image of he front. The database would be that much better. Other than that you guys are dong a great job.
It is awesome to be able to see both the front and bac of the cards. I like looking for errors that haven't been reported and mos not corrected. Also for people who may have trouble reading he backs it will be magnified once cropped and therefore easier to read.
