If you are tired of carrying around a bunch of membership cards in your wallet, why not scan them into your iPhone?
Apparently, someone has tried this and it works! Scan your membership cards into an iPhone gallery and amazingly enough a barcode reader can scan them...
So instead of writing down the numbers I scanned in the cards -front and back side- and stored them as images on my iPhone.
To test it out I went to the local hardware store and asked the girl behind the counter if she could scan the barcode from my phone. The first look I got was pure amazement. To her the physical card was transformed into a picture on a shiny device. On top of that the barcode was scanned successfully. The result; a slightly confused girl and a happy me.
@Anthony, this is not an app. All you need to do is scan your cards into your computer. Then in iTunes choose to sync those pictures to your iPhone. They will then be displayed in your photo galleries on your iPhone.
I have done this with a few other things as well. Works at Via Rail Kiosk for scanning in email train tickets and have my Air Miles card in my phone as well!
