So I was thinking about why my wallet is wearing a patch in my jeans, and I realize it’s because I am carrying about 20 cards, the majority of which I don’t necessarily need to carry, I just need the number. From there I figured the ideal way to fix this would be a phone app that I could use the phone camera to scan the card’s barcode, and it figures out what card it is and stores the number and barcode for me. Then I can just pull out my phone at scanners, say the airport, or for the number when I need to input it somewhere.

I sketched it up and then played a little with the design, and this is what I came up with. Then I bothered to look and saw there is already an app for that.

Oh well, fun times.
