    In order to understand how to protect yourself from payment card theft, first consider a few ways card information is compromised.   

    Data breaches

    The most newsworthy payment card theft is data breaches, with retailers such as Target, Home Depot, Whole Foods, Delta, and Best Buy being recent targets where their customers were the victims.

    Skimming/shimming

    A less impactful but equally common situation is payment card skimming/shimming.  In this malevolent technique, the bad actor places a secondary reader over the existing point of sale terminal that captures individual (per transaction) payment card track information and uses that information to replicate the cards.

    Online interception

    A similar “skimming” technique happens with online merchants, where a bad actor intercepts credit card information in transit to the merchant.

    Physical interception

    Physical interception of the card itself is another technique.  In this process, the bad actor steals the payment card information during the point of sale transaction, such as a cashier or restaurant worker making a copy of the card information before returning it to the owner.

    2. How to avoid being a victim

    Now that you know some of the basic methods of payment card theft, let’s consider how to avoid being a victim.  Here are a few ideas:

    Real time alerts

    Add real time alerts on cards and bank accounts!  While this will not prevent the “very first” transaction, you will quickly know someone is using your payment cards.  If unexpected transactions come through, quickly call your credit card company.

    Reconcile payment card bills

    Check your transactions!  Reconcile your transactions weekly or monthly, so you know the charges against your accounts.

    Use credit cards

    Use credit cards if possible!  Avoid using debit cards for retail and online transactions.  Be sure to understand your liabilities in either case.  With most credit cards, the consumer is not liable for fraudulent activity if the issuer is notified quickly.  With debit cards, fraudulent activity loss is normally capped at no more than $50 if the issuer is notified quickly.  However, if a thief controls a debit card attached to your checking account, your funds could be (at least temporarily) depleted.  The problem is that while the bank is likely to replenish the losses, if you need that money to clear checks before being restored, you may wind up overdrawn or having checked returned with non-sufficient funds (known as NSF).  The bank may reimburse their own overdrawn fees, but the merchants you have paid may not be as forgiving.

    Be alert!

    Most of all be alert!  Look for skimmers at point of sale transactions, and look for HTTPS leading the web address with online transactions.  In general, look for signs of trouble.  Use higher traffic machines if possible, since more people will have had the opportunity of identifying “not so right” situations.  If you have nagging questions about a physical machine or an online merchant, “just say no” and find a different merchant.  Remember, security starts with you.
