Yes I'm sure this is in the wiki and answered a million times but if someone could be so kind and just give me a very simple answer as I'm new to this - My wife and I currently have a Serve card, and live in NJ. Parents live in MD, and both have a Redcard with their socials and activated. They are coming up this weekend. Can they get or activate a Redcard for me and my wife in MD, and then bring it up to NJ this weekend? If yes, how do they go about doing it, and what do I do once I get it. The wiki was a little confusing to me and i just couldn't read 200 pages of this. Thanks in advance for the help.
