A man and woman from Riverview are facing 640 charges related to identity theft, officials said.
Dermaine Grier, 35, and Doris Thornton, 34, were arrested during a traffic stop on Interstate 75 north of Fletcher Avenue on Friday.
According to the Florida Highway Patrol, the couple, inside a black SUV, were stopped by a state trooper for violating the state's move over law.
The FHP report says the pair was acting "very nervous."
A K-9 was called to check out the vehicle.
No drugs were found, but state troopers found 238 pieces of stolen personal identification and two magnetic strip readers, which are used to skim credit card information.
The Florida Highway Patrol could not tell Action News where or if the skimmers had been used.
Each charge has a $2,000 bond attached.
As a result, Grier and Thornton are each being held on a bond of $1,280,000.
