NASHVILLE, Tenn. -- There are worries at Nashville International Airport that a credit card scheme is taking advantage of workers and possibly travelers.

Video: Airport Workers Concerned By Credit Card Scam

Some airport workers reported that their checking accounts were suddenly short of hundreds of dollars.

Airline employee Troy Scott said someone got his debit card numbers and went on a shopping spree in Texas.

"Somebody got gas. One (charge) was for $100. One was for $95," said Scott.

It appears some of Scott's co-workers have had the same thing happen to them, too. All of the victims said they used their debit card at an airport food vendor.

The Airport Police Department said they are investigating the cases, and an internal memo said the Secret Service is looking into the matter as well.

Another airline worker, Gonzalo Rivera, said he became a victim just a few weeks ago.

Several other employees said they also noticed new discrepancies in the last few weeks, so they started strictly using cash.

"This world runs on plastic, and if you can't use, what good is it?" said Rivera.

It appears that the problems first started in October. The scam then stopped, but recently more people began noticing money missing from their checking accounts.

The airport authority and the police declined to talk about the case because they said it is an ongoing investigation.

If members of the public have used their debit card at the airport and think there's been unusual activity on their account, they should notify the airport's Department of Public Safety at 275-1703.
