Business cards are a statement of personality and style, capable of conveying much more than contact information. They represent the creativity and intention, or ambition, of a company in a very portable format. As an historical artifact in the digital age, the business card is constantly in evolving and only those that truly stand§out are memorable. One way to achieve the noteworthy effect is through the use of interactive features - from a built in musical comb that plays a tune when strummed to an envelope business card containing a customizable mini-portfolio. Others include the use of color, unusual§shapes, or innovative materials such as wood, stainless steel, cotton, rubber and even temperature sensitive paper.
