Gift Card Hack
This is a clever hack against gift cards:
Seems they take the cards off the racks in stores and copy down the serial numbers. Later on, they check to see if the card is activated, and if the answer is yes, they go on a shopping spree from the store's website.
What's the security problem? A serial number on the cards that's visible even though the card is not activated. This could be mitigated by hiding the serial number behind a scratch-off coating, or opaque packaging.
