A news article about shoulder tap operations performed by my local police department said:

Police spokesperson Sgt. Riley Harwood said that during such sting operations, the underage decoys are not made to look older with different clothes or make-up, and they’re not taught any strategies of deception. “There are no tricks,” he said, explaining if a decoy is asked for a driver’s license or ID, they hand over a valid card that shows they’re under 21 years old. “There’s no math that needs to be done,” Harwood said of the obvious differences between underage and over-21 IDs. “People just need to do their jobs.”
