Card Skimmers In California: Here's How To Spot Them

Skimming devices to capture data on ATM and credit cards are a frequent problem throughout California, leaving residents wondering what they should be looking for to protect themselves when paying electronically or withdrawing cash. With these reports of skimmers at outdoor ATMs and gas stations come many questions, so Patch has tips to help you keep your money safe.

In California, the FBI recently charged more than a dozen people allegedly connected to a large skimming ring in SoCal. The Ventura County Sheriff's Department has apparently seen so many cases that it issued a reminder to the community "...to be careful whenever using their credit or debit cards for gas or to withdraw money from ATM devices."

The San Bernardino County Sheriff's Department in April reported a case at a bank ATM in Victorville, releasing the above photos of the device found there.

Now, let's go over the basics: What exactly is a card skimmer? It's a small device that affixes to a card reader allowing a thief to illegally collect the credit and debit card information of unsuspecting customers. Most commonly, card skimmers are put on ATMs, gas station pumps or self-checkout machines.

The typical ATM skimmer is smaller than a deck of cards and fits over an existing card reader, says PC Mag. Not sure what a card-skimming device looks like? This website shows various skimmers on ATMs, so you know what to look for in the future.

But what should you look out for so that you can avoid having your financial information stolen from a skimmer? If you see obvious signs of tampering, or the machine looks suspicious or different than normal, don't use it, experts say.

"One giveaway that you might be at risk is if a terminal looks especially wide — since any overlay skimmer piece will inevitably take up extra space," says Mic.com.

And as a Patch reader shared, be wary of ATMs at stores, because they might not be checked regularly for skimmers. Also, it’s not a bad idea to use cash at gas stations and other spots where thieves might have an opportunity to attach skimming devices.

Banking websites and police have tips to help foil skimmers. Last week, the Federal Trade Commission issued a warning to consumers, saying that while skimmers aren't new, emerging technology is making them smaller and harder to spot.

How to Protect Your ATM Card

• Use secure ATM machines under video surveillance or inside a bank lobby. They’re less likely to be tampered with.
• Pay careful attention to what the card reader and keypad normally look like on the ATMs you use most frequently.
• Don’t use an ATM if the card reader appears to be added on, fits poorly or is loose. Some thieves place a fake box over the card slot that reads and records account and PIN numbers.
• Inspect the machine for items that were installed over or around the PIN pad of the ATM. Look for an attachment on the ATM that contains a small hole that is pointed in the direction of the PIN pad.
• Lightly tug the area of the card slot. Most skimming devices are attached with double-sided tape for quick removal by the crooks.
• Cover the keypad with your other hand while typing your PIN. This is the best way to ensure that your PIN number is not recorded.

If the keypad backlight is off, that's another warning sign that a skimming device could be installed, the Mic.com article says.

Also, if the chip reader is deeper than normal, beware.

A rule of thumb (no pun intended): If your card goes so deep into a chip reader that you can't keep a thumb on it, that's a sign there could be a skimmer installed, Mic.com reports.
