I was able to take a moment with a guy who had been between jobs; he was looking for my feedback and wanted to make contacts that could lead him to a new position. We had a great conversation and I was actually considering helping him.
At the end of our conversation, when it was time to part, I asked him for his card so that we could follow up and connect him if I was to meet someone who needed the knowledge of him. It didn't have the main one; I have no way of following it or hooking others with it. My recommendation, get yourself a card. Even if you are unemployed, your business card is important. You can explore unique business card designs across the web and select the one that suits your profession.
