General question for those that travel with Global Entry, do you ever travel with your Global Entry ID cards? My whole family has Global Entry, and I recognize that Global Entry is already tied to the passports (so the cards are effectively unnecessary), but I feel the card would add one level of extra ID for our minor children that have no other forms of ID outside of the passports. Wise to bring them? Risky to bring them? Not even worth it? Just curious what others have done or do with their cards. Thanks in advance.
