COLUMBUS (Csaba Sukosd/Steve Levine) - A federal investigation that seized dozens of ATMS in Columbus has users addressing concerns over potential identity theft.

44 ATM's were taken by federal and local authorities headed by the Secret Service on Tuesday as they pursue an alleged money laundering scheme involving credit card and tax fraud.

Ohio ATM Sales and Services sells and operates independent cash machines across Central Ohio. Company inspectors regularly check the equipment for criminal activity.

"They go through a pretty extensive background check, make sure they don't have background in financial fraud or money laundering," said Eric Gray, a spokesman for Ohio ATM Sales.

ATM's affiliated with banks and credit unions are regulated by state and local governments, including most independent cash machine operators.

Gray said, the only financial info in the machine is the last 4 digits of your card number.

If a user has a problem with a machine, they should always check for a sticker on it that will have a number to call to report a concern or complaint.
