A woman using the "quick change" scam method walked out of Starion Financial with $1,700 on Thursday morning. 

The woman came into the bank at 350 S. Grand Ave. with 37 $100 bills and asked to exchange them for $50 bills, Sun Prairie police said in an alert to area businesses. After the exchange was made, she then asked for the $50 bills to be exchanged for $20 bills. The teller asked for identification before making that exchange.

Police said the woman could not produce identification, and she asked for the $100 bills back, giving the stack of $50 bills in exchange. After the woman left, it was determined that she had slipped 34 of the $50 bills out of the stack, concealing them in her hand.
