UPDATE: Police in Trenton say that have found another Bluetooth device at a gas pump.

The device was spotted at a Circle K gas station located at the intersection Highway 136 at Main Street.

Police say the device was found by an attendant who was changing out the receipt paper at the pump.

The device had been removed and the pump is safe, according to police.

They suggest that whenever you have a doubt about a gas pump's credit/debit card reader, using cash to pay is your safest option.

PREVIOUS STORY: Every few months it seems like another scam is being reported.

In Dade County, thieves are trying to steal your money at the pump, and you may not be able to easily tell the card reader has signs of tampering.

"First time I've ever seen one," says Kristie Walker who was working at the Citgo gas station on Highway 11 in Trenton.

A gas pump tech noticed something that wasn't supposed to be there, and brought it to Walker.

“A little white device. It has a green blinking light that was connected to the device” describes Walker.

Trenton police confirmed that little white device was actually a Bluetooth-connected credit card skimmer, which made it tricky to spot.

"It can be put on there and the person never has to come back to the store and just be in the vicinity. Download it to a laptop and get all of your pin numbers, everything," says Trenton police chief Christy Smith.         

Now a usual tip to avoid skimmers is to wiggle the tip of the card reader, but that may not always work says Smith.

Chief Smith says you can use your mobile phone as one way to spot the device.

“Go to your Bluetooth and will activate and try to connect and if you see several numbers down this list. That'll be that device trying to connect to Bluetooth, or your phone trying to connect to that Bluetooth."

Other tips Smith suggests:

  • Make sure to use a credit card.
  • If you don't have one, use the credit function when swiping your debit card.
  • Use the pump closest to the cashier.

Or if you don't want to use a card at all Chief Smith says, "Cash... cash is always the safest option.”

At this time only one report has been made.

The Citgo gas station has been swept clean and is working with police with the investigation.

The store owner says that no skimmers are present at the station and it is safe to use the station's gas pumps.

PREVIOUS STORY: A credit car skimmer has been found at the Citgo Gas Station next to Trenton City Hall on Highway 11.

There have already been reports of resident's accounts being hacked.

A statement from Trenton City Police Chief Christy Smith, posted on Facebook said: 

"I regret to inform all of you who had your account hacked, that the rep did find a skimming device on one of the pumps, and it has been taken into evidence and reported. Always use caution as this can happen anywhere and to anyone. We are thankful this was looked into and taken seriously by the store owner, who had the internal devices checked."

Here are some tips from experts on how to spot a skimmer:

  • Make sure the gas pump panel is closed and doesn't’t show any signs of tampering.
  • Most stations now have a security label that will read "VOID" when it's been tampered with.
  • Also, it is good to wiggle the card reader because if it moves that could be an indication of tampering

Experts also say to be vigilant and always monitor your credit card and bank accounts regularly to spot unauthorized charges

If you're really concerned about skimmers you can pay inside rather than at the pump.

Another option is to use a gas pump near the front of the store. Thieves may target gas pumps that are harder for the attendant to see.
