The concept is simple; Scan the front and back of all your barcoded membership cards, and carry them around in your 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.
My take: I’m going to try this on my library card and see if this works on my Palm Pilot T|X.
