Are NJ 7-Eleven stores being targeted?

On April 1, a customer at a 7-Eleven on Route 130 in Cinnaminson found a skimmer and called police.

In this case, police were able to use surveillance video to determine the device was installed on March 22 at 9:21 p.m.

Cinnaminson police are warning any customers who used their debit or credit cards at the 7-Eleven to review their bank statements for possible fraud activity.

Despite the close proximity of the two stores involved, investigators have not linked the two incidents at this time. The investigation into the Pennsauken skimmer is ongoing.

How do I protect myself?

Skimmers can usually be spotted by doing quick visual or physical inspections before swiping or inserting a card.

Look for tape or sticky glue on the ATM before using it. Look to see if the card insert area seems bulkier or thicker than usual. Is there anything hanging from the ATM? A wire or a cord hanging from the machine could be a telltale sign.

Also, be sure to run your fingertips over the card insert area and the keys before starting. If anything feels loose, that’s also a sign the machine may have been tampered with.

If you suspect the credit card reader has been compromised, don't insert your card notify the store and call police immediately.
