A contact card is a small paper or electronic document that contains essential information about a person or a business. Synonyms for contact cards include business cards, networking cards, name cards, information cards, and identity cards. Business cards are commonly used by professionals and entrepreneurs to introduce themselves and their businesses to potential clients or partners. Networking cards are also commonly used at business events or conferences to exchange contact information with people one has met. Name cards are similar to business cards, but they often contain only a person's name and title. Information cards and identity cards, on the other hand, are used to record personal details such as contact information, identification, or medical information.
