As fake IDs become more sophisticated, technology is catching up too.
A new app called Intellicheck scans the encrypted bar code on the back of a license and verifies that it matches government data.
It's more effective than many systems stores already have in place, like scanning the bar code on the back of an ID merely to compare it to information on the front.
"We had a 40 percent increase in the number of fake IDs that we seized from young people," says Russ Hanna of the Mississippi Alcoholic Beverage Control. "So it really helped my agents. It was a game changer."
The maker of Intellicheck says hundreds of stores that sell alcohol across the United States are using the app.
Authorities hope the technology will help them in the fight against underage teen drinking, especially during spring break, when cities like Miami see a spike in underage drinking and driving.
"Most college kids do not social drink like adults," says Hanna. "They drink to get intoxicated. So if we can stop a few of those from drinking and driving, we are saving lives, no doubt."
