Doing my initial roll out to show to a select few friends, two questions have come up with them, 1. say 3 or 4 get my digital genuis card and open on their phone and ask questions, is the "chat" sequence unique to that user? That is person A, will not see the chat of person B? And 2. when someone gets my genuis card, how do they save it on their phone, is there a way to save to their screen as "Hal's Biz Card" like the apps are? thanks
