I mean... The wrist band IS communication. Not your preferred method and that's fine. I tend to be open to engage in conversation and a handshake, but I will not be the one to initiate. But I also know that some of the associates that our business conferences are incredibly shy, but since attendance was mandatory they're there anyway. I would really appreciate something like this for them. They would engage even though they don't want to because they're afraid of being rude
