Do you have a business card? If you do not you need to get one. You do not want to attend a networking group or interview without one. Your business card says something about who you are. It should have your name, title, email and phone number at the least on it. Some people like to place a saying about their business or what they are known for on the back of the card.
I thought this was a good idea and use to have a saying on the back of my business card until it was suggested that I leave the back of the card blank. This was done to allow the person who I left the card with a place for them to write a note on the back of my card. People write where they met you, their impression, or as a reminder to send your some type of communication. I left the back of my business card blank from that time forward.
I recommend using a high quality stock paper for your business card and recommend getting the card laminated too. Your business card will feel rich in hands of the person you give it to and leave a good first impression. Be sure to obtain the business card of the person you are speaking too. It is an opportunity for you to reach them again in the future.
