Your business card is only a tool. It is not who you are and will not, on its own, get you in the door anywhere. Business cards are great for jogging the memory, especially when you are at an event where you meet a number of people. They can also help to reconnect with others later on, after the event.
I was given a business card at one event by someone who felt more like a Vegas blackjack dealer than what he actually was. He didn't bother to shake my hand, make eye contact, or even introduce himself until I called him on it. I won't even name the industry because it really doesn't matter. These "handshakers" come from any industry and every level, unfortunately. Somewhere along the line they missed the meeting about how important it is to really listen to people first.
The next time you engage with someone, make the encounter the top priority. When they give you their card, look at it so you can connect the person with the card. It is the person, not the card, that you should remember the most. As far as titles go, "business card handshaker" is not one you want to assume.
