The site provides a handful of basic templates to choose from, then lets you fill in as much personal information as you'd like (business name, phone numbers, etc.). Next, you choose from a palette of about 100 colors for the text, accents and background. The biz-card maker then produces a downloadable PDF with either a full sheet of cards for home/office printing or a single card you can give to a commercial printer.
