Potential counterfeiters can turn to the black market and look for materials for making counterfeit IDs, such as "blanks" (laminates with holograms usually wrapped around a driver's license). And/or they may try to bribe employees of fake florida drivers license DMV, military bases, U.S. Post Office, or banks to obtain these materials.
Some IDs are obviously fake. For example, the height of the person does not match the height on the fake ids. Otherwise, the person looks too young to celebrate his birthday. But many merchants simply don't have the skills to detect fake cards, or they ignore mathematical operations to determine whether the ID holder is old enough.
