Official identification cards for the rank and file are a thing of the past. Whenever a brother has to visit the jail/prison to see a prisoner, thee are cards that the elder body will give them.
If individual JWs have identification cards, they are directed not to use a WT symbol or name on the card.
JWs have never worn badges to the doors except during door to door campaigns during a district convention and it would have been the lapel card for the convention.
