I use 1Password on my iMac (Lion) and iPhone (iOS 5.0), and love it! I do have an idea for a feature request that would be really handy in emergency situations. I would love to have the ability to scan my cards as images on the Mac, have these images sync to the iPhone, and display those images when needed. For example, let's say I am at my doctor's office and realize that I have forgotten my insurance card. I would open up 1Password on my ever-present iPhone, open the wallet entry for my health insurance card. Then I would tap the "View card" icon and the scanned image of the card would appear in full-screen display. To see the back of the card (another scanned image), I would simply swipe the screen to the left, and the back of the card would appear. I would also have the ability to pinch-zoom in and out while viewing the image.
I really do hope you can implement this handy feature. Keep up the great work!
