Ours have two different holograms on them and a barcode like thingy on the back. They're supposed to be hard to duplicate. Here managers at gas stations take a class on how to recognize fake ID's and pass the info on to their employees, even out of state ID's.
But if you decide to get one, you better make damn sure you don't get caught cause the penalties are getting tougher. This is what you get for it in SC:
using a fake id : To use someone else's driver's license or personal identification card.
First offense: Up to $100 fine or 30 days imprisonment; driver's license suspended for 90 days.
Second or subsequent offense: Up to $100 fine or 30 days imprisonment; driver's license suspended for six months.
S.C. Code Sections 56-1-515(2), 56-1-515(4), 56-1-746(a)
using an altered id: To alter a driver's license so as to provide false information.
