If you have TOO MUCH on your name badge, it is hard to read; if you have too much on your name badge, you take away the opportunity for those you meet to ask questions; if you have too much on your name badge, it may scare people off !!!
A name badge is an identifier and perhaps even a conversation starter. Sometimes, depending upon the industry of the person, I have suggested a colorful name badge with JUST HIS/HER name on it, nothing else. This will FORCE the other attendees to say “What do you do?” and that leaves the answer portion WIDE OPEN, depending upon the event and the other attendees in the room.
Be creative and make your Networking experience FUN. People will WANT to meet with you for coffee if they have noticed something special about you, so give them that chance.
