Look up the states most often presented as proof of age to determine
whether the ID scanner needs the 2D bar code scanner. If
located in a non-tourist or non-college, magnetic striped state, the
CardVisor I, II, III or IV package may be sufficient. If in a
state with a 2D bar code, then the 2D bar code scanner is required.
Many states have recently begun issuing licenses with 2D bar
codes. In some states they are adding a 2D bar code to a
license which has a magnetic stripe and in others states the license
did not have a magnetic stripe. States take 4 - 6 years to fully convert all
licenses to the new formats, with the youngest drivers getting
the new format.
