1. The exhibitors come with the purpose of selling their stuff, not buying yours. So it naturally works best to hear what they have to sell first, while you genuinely try to figure how it may be useful to you. Whether or not you know if and how you may use their offering, ask them questions based on what you are trying to achieve, in the process making them also think about how their offering could be suited to help you. They are still trying to win a sale but by this time a rapport is well established and it is easy to get purely to your own work. Even if no potential deal is sensed, I have generally come out with some useful help or advice.<p>2. You can take notes on the business card itself the moment you are out of the conversation. It is sometimes easy to loose track by the evening even given the number of people you may meet during the day. You should be aware of this [1] though.<p>3. It is a lot easier for people to remember your face than your name when they first meet with you. So absolutely consider having your picture on your business card. If they understand the core of what you are trying to do, they'll also remember it clearly together with a memory of "some guy" who explained it to them. So include your tagline or pitch on the business card itself, on the rear if needed.<p>[1] <a href="http://www.linguist.com/services-japanese-card.htm" rel="nofollow">http://www.linguist.com/services-japanese-card.htm</a>
