MADISON, Wis. (AP) -- The University of Wisconsin-Madison has given seven liquor stores and a grocery in the city electronic scanners to help them spot fake IDs.

The scanners are part of the university's effort to curb underage drinking. It has used similar ones on campus since last year.

Clerks still must make sure card holders are the people pictured on the IDs, but the scanners verify the age and other details on the cards.

Richard Schober owns MacTaggart's Market, one of the stores that received a scanner. He says he probably wouldn't have bought the $1,000 scanner but with the cost covered, his store will use it.

Stores using the free scanners have promised to turn over confiscated IDs to the police every three months.
