Credit Card Fraud: Tiny Grains of Sand Can Result In Large Piles

I learned of this scam against credit cards while volunteering during my shift in the kitchen at our church’s bingo one night.

A small charge, an amount under a dollar up to a few dollars, appears on your credit card statement.  Due to the insignificance of the amount, you don;t bother spending any time trying to figure out what it was for, and having it reversed off your account.  You try and recall where the charge could have come from, perhaps an adjustment to a legitimate purchase.

I never thought much about thieves stealing million of credit card accounts, and simply charging a few dollars to each stolen account.  But as it turns out, that’s exactly what they do, and a few dollars charged to millions of accounts, results in millions of dollars.

I went home that night and checked my credit card statements, and sure enough, I found these insignificant charges on my account.  The total of them do not warrant my doing anything about it, but they are there.  I’ll bet if you look, you’ll find them on yours as well.

Here’s the link to an article where the FTC just busted a very organized ring was stealing credit card accounts and doing this very scheme.

Credit card skimming… watching for new opportunities (or vulnerabilities).

I just returned from speaking at a conference in Miami.  I checked into my hotel, and as part of my debriefing from the travel, I found the in-room safe to safely store my laptop, camera and other electronic devices.

As I read the instructions it dawned on me that we used our credit and debit cards in many different contexts beyond store purchases, gas purchases, red box terminals and ATM machines.

At the airport I had to use a credit card to retrieve my boarding passes – the airlines call it “self-service” checkin.  Nothing self-service about it, we had to get in line both ways due to system issues.  I wondered what system was behind the self-service terminals that hundreds of thousands of travelers insert their credit card into every traveling day, and more importantly, what safeguards were in place to protect my card information from skimming or theft.

The safe in our room had two options – enter a private code or swipe a credit card on the reader.  The same card used to close the safe would be required to be swiped to re-open the safe.  I wondered what systems were behind the safe tracking my credit card information, and more importantly, who had access to my card information when I swiped.  I chose to enter a four digit code, as I had no way of knowing if dishonest employees could access all the cards swiped on the room’s safe.  And then I wondered how many safes were in this one hotel – hundreds.  In all the rooms in all the hotels in the US alone – thousands…

An individual attending one of my sessions in Miami asked me what I suggested for a replacement to using debit and credit cards due the high incidence of skimming.  She asked if we should switch back to cash only.  I responded that if we did that, the number of personal robberies would certainly increase.

The solution if to be prudent where you use your credit card, monitor your card’s activity, loose your debit card (and switch to a credit card), and remain vigilant.

Skimming… not the redbox terminals. What’s next?

In preparing for a presentation I am making at University of Connecticut next week, I was searching the Internet tonight for images of credit and debit card skimming.

I came across a frightening image.  It was a picture of a redbox movie rental station, focused in on the credit card swipe area.

Much to my surprise I learned the folks stealing our credit card and debit card information have been installing their card skimming devices onto redbox stations.

If you are a redbox user like myself, you need to start watching for signs to ensure that a skimming device has not been added to the redbox station you use.

Here is the URL to the redbox image to help show you what to look for:
