As many of you I had my wallet filed with membership and other reward cards from the local hardware store the grocery shop and the rest of it. Some cards used regularly some used only once a year.
As mentioned in the post from the unclutterer most of the companies only need the number from the card. The magnetic strips are hardly used and the barcode is just a store for the number. 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.
