Back when all this started, with the first lockdowns, some were concerned that if they left their homes and were not an "essential worker" they might be subject to arrest. While that might have been an intent of some of the more extreme politicians out there, in reality people weren't arrested that I know about. Where I live, the Sheriff Department outright said they weren't going to be enforcing the lockdown like that.

So I suspect the card will be similar. It will probably not be used by most places as a key to entry. Or at least, not enforced that way by peace officers. Some private places, I suspect, will use it as an excuse to bar people they don't want around anyhow - you know what I mean.
