Real estate businesses who deal in buying or selling houses, should have a good business card that has a house logo or their brand icon in the middle of it. Try to keep the black background orange house business card as minimalistic as possible. In some cases, a business card typically includes the giver’s name, company or business logo, and contact information such as street addresses, telephone numbers, fax numbers, e-mail addresses, and website. A business card is a 2 by 3-inch rectangle of card stock, although creative custom card designs have been done using a variety of materials such as wood or cloth, or paper.
