A blogger named Albert Alberts, scanned all his membership cards to his computer, synced them to his iPhone and made a new photo album called “WalletCards.”
Membership numbers, bar codes, security codes, expiration dates, etc… are now right at his fingertips anytime he needs them. And the scanned bar code images can even be scanned directly off the iPhone’s screen at the register!
There is a downside to this however. The scanned cards on his iPhone obviously can’t be swiped in a credit card machine. So this technique won’t work every type of card, but it can at least help slim down your wallet a little bit.
