People remember you by what catches their eye. Cool colors along with company names and unique logos on physical business cards can leave quite an impression. Not only will you have a nifty case to organize your clients' cards, you can still write a personal note on your business card. That's another bonus that won't be forgotten. If Wi-Fi connections become a problem--as we all know that can happen--there is always the good old-fashioned calling card case. All the more reason to consider having one!
