WATERLOO, Iowa (AP) -- A 29-year-old Waterloo woman who had been working as a waitress has been sentenced for stealing credit card information from her customers to make new cards.

The Waterloo-Cedar Falls Courier reports Melissa Zehr was sentenced last week to 15 years in prison. She'd pleaded guilty to theft and credit card fraud.

The sentence will be served at the same time as a sentence for crimes in the Iowa City area.

Police say data from the cards were taken from the magnetic strip and then recorded onto another magnetic strip.

The second strip was placed on an ordinary pre-paid Visa card, and a name was embossed on the front. Purchases were then charged to the victim's account.

Court records say nearly 20 customers had complained their cards were hijacked.
