There's tons of information you can put on your custom business cards. All of it may seem important to you, but there is specific information that is essential to help you grow your network. Some core contact information to include on your plastic business cards is your name, logo, and contact information. Only put your professional contact information onto your plastic card to prevent prospective clients from calling your personal phone. Put other information onto your business card if it is needed or relates to your company. Cards that are too busy or have too much information are hard to read and will confuse potential clients.
