You are spot on Dave. I know on one of our cruises we did in fact insert our card into the readers each time. I almost think it was on the same cruise that a small outbreak started and we encountered wait staff at the entrance to each food venue that herded everyone to the sanitizers before entering the restaurant. Everything was served by ship staff only and no one was allowed to handle anything. No one spoke of any illness you could just tell that something was going on. Better safe than in quarantine !
