A calling card is a small card carried by an individual to present their name and contact information to others. It is also known as a business card or visiting card. Other synonyms for calling cards are personal card, name card, introduction card, appointment card, or identity card. The term "trade card" is commonly used to refer to a card given out by a business to promote its products or services rather than for personal purposes. In the digital age, the term "eCard" has emerged, which refers to an electronic version of a calling card that can be shared via email or social media platforms.
