Your corporate identity defines who you are as a business and how you want to be percieved. A business card is so much more than just a contact information hand-out. It's very likely the first piece of collateral that a potential client will see and therefore invaluable. In addition, your logo is the graphic abbreviation of your company and as a representative, you. Combined, a professionally designed corporate identity package that is consistent across all your collateral materials helps to boost a customers confidence in your abilities.
