What is the purpose of a business card?

The primary purpose of a business card is to tell a person's name and title and the name of their business. It also gives appropriate contact information.

According to Entrepreneur, an interesting business card can tell people a little bit about a company's products and services by its design. Inventive business cards stick in people's heads, reminding them of the person when they are ready to do business. Because they are tangible pieces of paper, business cards can be passed from one person to another, which can give companies exposure to more than one client. People often keep business cards on them to promote themselves or their companies.
