KNOXVILLE, Tenn. (WVLT) - Many Knoxville bars are now requiring two forms of ID thanks to an increase in fake drivers' licenses.

"On the weekend we usually get about 5 or 6 a night, usually come through here. Some nights we get more like 12 or 15," said Will Bowling, a bouncer at Goalpost Tavern.

Fake IDs have been popular for University of Tennessee students for several years.

"Some get them from people they know. I guess that's probably the easiest way. I've known of people getting them on the Internet, but I just don't think that's smart at all," said student Hannah Rankin.

Now new technology has made IDs passable with real bar codes easily accessibly from international vendors.

"A lot of people get them from China. I've heard about them coming over in some type of electronic or video game, and they have to break it open and they get it that way. It sounds crazy but it happens," said student Collin Napier.

But technology advances have also made the fakes easier to spot.

"With the new technology a lot of them have black light feature so if you shine a black light on it, depending on what state it is, it can blow up. Some things can appear," said Benjamin Bowling, Goalpost Tavern's manager.

"It'll be smudged or they'll be a crease in the lamination or sometimes there's supposed be a sticker somewhere where there's not one. So there's always something on each ID I can find that's not supposed to be there," said Will Bowling.

Bar owners who fail to catch those using fakes are subject to fines of $1,500 and the possibility of losing their liquor license.
