Ive tried so many of these apps and finally settled on BCR Pro as its the easiest to use, the most reliable to properly capture the card details and require the fewest edits.
I also like the ability to crater my own card and send it out to clients via QR code, SMS or email with a quick send.
If you have a lot of cards to capture this is the app for you, its a huge timesaver.
No capture app is perfect but this comes close.
