Just fyi for people using the app, or deleted it because it didn't scan. I sent an email the other day asking them to update the app for the droid. The barcodes were very tiny on the screen and at least one of mine didn't even scan because it was so small and lines packed in so tight. I just got an email yesterday (didn't push to my phone, maybe b/c i have auto sync, bt, gps, everything off) The develops updated the server side and now the barcodes are like twice the size. They said to delete your current card and re-add it and it should be bigger. Tested two of mine and it is much bigger and more readable.
