A business card is a representation of the person, so show it respect. Do not write on a business card in front of the person who just handed it to you. When you accept a business card, look at it for a moment.  If you like the card, compliment the person on the business card.  Present your business card with your name facing the person.  Do not cover the business name with your finger or thumb. 

When working with people from other cultures, learn their business card protocol.  In China, present and receive business cards with two hands. Spend at least a minute or two looking at the card, as a sign of respect.  In areas of the Middle East and Africa, present and receive business cards with the right hand only.
