7 reasons your credit card gets blocked
Plus: 7 tips for handling it when it happens to you
your credit card company stops a thief from charging fraudulent expenses to
your card, you're thrilled. But what happens when they mistake you for the
$6.89 billion in fraud losses in 2009, credit card companies eager to stem the tide are continually beefing up their anti-fraud measures, relying
on sophisticated computer software to flag suspicious transactions. Trouble is,
what looks like a red flag to a computer may just be you trying to make a
mundane purchase. Then, all of a sudden, your card's declined, leaving you
red-faced and frustrated.
what looks bad to your card company? Anything out of the ordinary. "The
credit card companies -- Visa, MasterCard, American Express, Discover -- all
have their own proprietary technologies that look for anomalies in your
spending habits," says Robert Siciliano, a McAfee consultant and identity theft
expert based in Boston. Siciliano suggests that each transaction is automatically
analyzed for up to 200 different data points, everything from where you live to
what you normally buy to how much you're spending, to determine the likelihood
that you're the one actually making a particular charge. If the analysis
doesn't add up, your card will be blocked and your next purchase declined.
What triggers a block
Card issuers won't go on the record about
specific red flags -- as Siciliano points out, "That'll only give the bad guys
an edge." But according to experts and hapless cardholders who have experienced
a block, these shopping habits may lead to hassles:
- Shopping where
you've never shopped before.
"I've had calls from my card company saying, ‘We've detected
unusual activity.' It wasn't unusual, but it was a different pharmacy than the one I normally went to,"
says Denise Richardson, a certified identity theft risk management
specialist and author of "Give Me
Back My Credit!"
- Making several
Janis Badarau, of Lavonia,
Ga., sometimes hits three grocery stores in a row to find what she
needs and take advantage of sales. But a few months ago, she was so speedy
that by the time she swiped her card at the third store, it was declined.
"I called the bank when I got home, and they told me that shopping
at three supermarkets within an hour or so was considered 'unusual
activity,'" Badarau says.
- Charging something small, then
Criminals sometimes test the waters with a stolen card by charging a tiny
amount -- say, a song on iTunes -- before moving on to a triple-digit purchase.
That small-big pattern in your own buying habits may result in a declined
- Shopping away
from your home base.
That's especially common when you're moving. "If
my billing address is Massachusetts and I'm buying a washer and dryer in
Idaho, that's an anomaly, because why would I buy a washer and dryer in
Idaho if I live in Massachusetts?" says Siciliano.
On the road, any purchase from gas to restaurant meals can trigger a
block. While that's long been true for travelers abroad, it now happens domestically,
too. "Once my travel to L.A. flagged it and I spent 20 minutes
verifying transactions," says Traci Coulter, of New York City. When she
asked what caused the card to be declined, she was told, "a taxi, a charge at the
airport, in-air Wi-Fi and a rental car hold" -- all standard travel
things in different geographic regions on the same day. During
a cruise, Janet Gillis, of Tampa, Fla., used a card to get money from
an ATM on the ship, then she later made a purchase on-shore in Belize. For
the rest of the trip, her card was declined. "Apparently, the ATM on board
the ship is registered to a Miami location, and several hours later, I was
purchasing something in Belize. To them, it looked suspicious because the
transactions happened so close together," says Gillis. Online purchases to
merchants in different parts of the world can trigger the same flag.
- Dealing with
When Siciliano wanted to make an addition to an online
purchase, he contacted the company, but the second transaction they tried
to process was declined. The card issuer "thought that the merchant was
taking advantage of my card number."
How to handle a block
your card company suspects suspicious activity, sometimes you'll get an email
or a phone call asking you to verify a purchase. Other times your card is
simply declined, with no advance warning and no information why, and it's up to
you to call your issuer and sort out the problem. Follow these tips to minimize
the hassle (and humiliation) of a blocked card:
- Carry backup
You'll be able to offer another working card while you sort out the
problems with the first.
- Keep your card's contact info handy.
"Have your credit card company's toll-free number as one of your phone
numbers in your mobile," recommends Siciliano. "If a card is declined, you
know who to call."
- Tell your card
company when you're traveling.
Advance notice doesn't always keep your travel purchases off the
"suspicious activities" list, but card companies recommend it. In the same
vein, "Give your creditor your cell phone number,"
says Richardson. "If they only have your home number on file, that can be
a problem, too."
- Use a prepaid card. When
you travel, a preloaded card gives you the convenience of credit without
the hassles. (You do lose the protection, however, so that convenience
comes with a price.)
- Get texts. According to Chase
representative Gail Hurdis, customers can sign up to receive a text
message within minutes of a flagged transaction and can indicate by text
whether they recognize it. If they do, the account is updated and the
transaction cleared instantly.
- Provide a new
When you move, quickly update your billing address so your card company
recognizes your new home base.
- Ask for
When Linsey Knerl's card was erroneously declined, the store cashier
refused to accept any other card, forcing Knerl to abandon a cart full of
stuff. The Tekamah, Neb., woman wrote a letter to her issuer
expressing her disappointment. "The credit card company actually gave me a
rewards points bonus for my troubles -- enough to buy a plane ticket the next
time I traveled!" she says.
Annoying as it can be to get blocked by mistake,
remind yourself that it's a sign that your credit card company's got your back.
