A few years ago I decided that my wallet had become too thick. It contained the usual assortment of cards including driver's license, library card, debit and credit cards and also half a dozen rewards cards. So I decided to do something about it. I scanned in the face of all of my rewards cards, and then scanned the bar codes on the back and then tiled them all together in Photoshop:
I scaled the bar codes as large as practical and have never had a problem with them scanning at the cashier. After I printed out the card, I covered both surfaces with 2 inch wide clear packing tape to protect it.
Now when a cashier asks me for my rewards card, I offer them the card and isolate the bar code they want to scan between my fingers so the scanner does not get confused by reading the wrong bar code. A number of cashiers have complimented me on my clever idea so I thought I would share it with my readers.
Chiropractors are aware that sitting on a thick wallet can contribute to a whole host of issues ranging from scoliosis to neck pain, and I certainly feel more comfortable now that it is nearly 1/4 inch thinner.
