In Florida I am not sure what "card" I would be looking for. The license number on the permit is for the licensed EC that pulled it (who is not likely to actually be there). There may be a sub permit application for another licensee but unless you saw a different name on the truck outside how would I know who was doing the job? The 5 counties around me don't have a journeyman's card so any employee of the listed EC is an "electrician" if he says he is.
