The Pennsylvania Liquor Control Board is testing out a pair of wine vending machines located inside supermarkets, the Associated Press reported July 8.

Making a purchase isn’t as simple as inserting your money and making a selection, however: buyers must run their state driver’s license through a card reader and blow into an alcohol breath sensor first.

Currently, Pennsylvania limits wine purchases to state-run liquor stores, which many customers find inconvenient. If the pilot test is successful, however, the state could authorize placement of the machines in about 100 other retail locations.
