One option is to have your business cards displayed in an upright holder. Some models like this even come with a pen and pen holder so you can easily find a pen if you want to make a note on a business card or sign it before you give it someone.

Another option is to have a case that is slightly bigger than business cards. If you are organizing business cards that are not your own you can sort the cards in alphabetical order. If you are using this case for you own cards you can conveniently take with you, keep in your car or in your briefcase or purse.
