If your employer doesn’t supply business cards, consider having your own personal contact cards printed.
To make the most of your networking opportunities, you will want to carry the right tools.  It is good practice to carry a supply of clean, up-to-date, crisp business cards.  Remember that first impressions last, so don’t be tempted to rely on an out-of-date creased business card with your old job title on it!  If your employer doesn’t supply business cards, consider having your own personal contact cards printed.
