Maine’s attorney general is warning consumers of a scam that offers a credit card in exchange for $200 and bank information.

Attorney General Janet T. Mills said a new so-called “advance fee” credit card would require pre-payment and bank account information in order to receive a credit card with a credit line of $2,000.

Southern Maine’s PeoplesChoice Credit Union reported the activity, saying that fraudulent callers claim to represent PeopleChoice Savings, Mills said Thursday in a written news release.

The credit union said it had gotten 25 phone calls over the past three weeks from people contacted by the scammers, according to Mills.

“PeoplesChoice Credit Union has nothing to do with this illegal offer,” said Brenda Piecuch, compliance manager and information security officer at the credit union. The credit union has branches in Biddeford, Wells, Saco and Sanford.

Consumers should never offer bank account information over the phone or Internet without confirmation of the identity and location of the person requesting that information, Mills wrote. “Verify, verify, verify,” she said. Any legitimate bank in Maine would only ask for that information in person, she wrote.
