Reason: Some cards give the entire credit card number on both the front and the back. A crook who finds only one half of the card might be able to figure out the complete number by combining the numbers on the back with those on the front.
Shred unwanted credit cards or cut them into many small pieces, and dispose of the bits in separate garbage bags. The old recommendation to cut an old card in half is no longer enough.
