Trashing old credit cards? Be careful
You're asking for big trouble by simply cutting up and tossing your old credit cards. Instead, try these 6 methods for foolproof data destruction.
In a world of escalating identity theft, one man's trash is another man's excuse to help himself to a new line of credit.
Making a few halfhearted snips with the scissors to your old credit cards just won't cut it anymore. Dumpster divers intent on looking for account numbers do not need much. Experts say even shredded cards can be pieced together by an earnest thief.
"Anything you put out on the street, you're saying, 'Have at it,'" said Jim Stickley, the author of "The Truth About Identity Theft" and a security expert who has done more than his share of picking through trash to identify security breaches for corporate clients.
Much of the identity theft that touches millions of Americans each year can be prevented with a few simple measures that take less than a minute. Here are six tips for doing it right:
1. Properly cut up your credit cards
Scissors can do a fine job of destroying a credit card -- provided you use them correctly.
After suffering from several cases of both credit card and identity fraud, blogger Jim Wang of Bargaineering.com developed a system for cutting his cards that involves slicing each set of four numbers into six pieces (see the video "How to destroy a credit card" for a demonstration). Make sure you also cut through your signature and the magnetic stripe on the card.
2. Completely shred your cards and documents
Shredders can also do the trick, but be sure your shredder is designed to handle credit cards and has a crosscutting function.
Such machines are typically twice the price of a normal shredder but still less than $100 -- worth the price to protect your credit.
3. Destroy magnetic stripes and chips
Wang recommends taking an extra step to deactivate a card's magnetic stripe and, if there is one, its RFID chip. To scramble the data in the magnetic stripe, run a very strong magnet along it.
Apply scissors or a hammer to the chip embedded in the card, as "all the information stored on the card is also stored on the magnetic stripe and the chip," Wang said. This takes just a few extra seconds.
4. Trash tip: Bag the pieces separately
To prevent curbside identity theft, deposit the pieces of your destroyed credit card into different trash cans around your house. The idea is that some receptacles are emptied more frequently than others, so if half of your destroyed credit card goes to the curb with the kitchen trash one week, the other half will go out with your office trash a different week.
