How do I have 1Password store my rewards cards' front, back, and barcode?

Thanks, Alvin, for the step-by-step instructions! I had forgotten about this feature.

When I followed your steps, I quickly realized just how clunky the feature is. I sure hope the 1Password Team will develop this feature to easily add reward cards that will actually read with one's iPhone Camera the member's numbers, the PIN, member's name, etc. to automatically populate the fields. I also hope they create a feature that will incorporate the iPhone Camera to automatically crop front and back images of a membership card, and then make it visible instantly both as a thumbnail image and as a full size image. That's what I would like-- and I'll bet everyone else would like that as well! Anyway, thanks!
