In this business environment a business card is essential. The TIE Institute is on Slideshare and spell out the need for a good business card. I cant count the number of times I have requested a business card from a representative. Why would I have to request a card? A card should be offered during the introductions. Another mistake would be to be out of cards. This indicates poor planning and a red flag. I scan important cards into my smartphone. Business cards can be printed here. It is important to make sure the cards are professional and clean. A poorly put together card sucks.
