I am extremely happy with this card. I purchased one green and one red. I usually wear the green one, but the red is in my car for backup in case I forget. My second job is driving Uber Eats so I visit a ton of restaurants every day. Before the card, some places like McDonald's, BW3, and Walmart would give me a rash of crap for trying to enter without a mask. I found this card and started using it. No problems at all since even the same restaurants with the same mask nazi's let me by. The worst is an occasional eye-roll which I can live with.
