Business cards are cards bearing business information about a company or individual. They are shared during formal introductions as a convenience and a memory aid. A business card typically includes the giver's name, company affiliation (usually with a logo) and contact information such as street addresses, telephone number(s), e-mail addresses and website. Traditionally many cards were simple black text on white stock; today a professional business card will sometimes include one or more aspects of striking visual design.

Business cards are frequently used during sales calls (visits) to provide potential customers with a means to contact the business or representative of the business.
