I forget my business cards all the time. Heck the first day of CES I had to scramble to find cards to hand out to people, now Speck has an inventive solution for business people like me who are a bit forgetful. The Speck Candy Shell Card case for iPhone 4 devices features a wrap around, protective design in various colors, while the back side features a special slot to hold business cards.
Sure the backside only holds 3 cards at one time, any more cards than that would make the case bulky, but that should be enough cards for you to realize that you need to go pick up more cards before you do any more business.
The case featured above is a fairly bold color choice, however there are other options, take a look at other case color options below:
Speck has always been good at adding a splash of color to their products so you can probably expect to see more color options in the future.
