MOO's CEO suggested some new ideas on design a business card which mainly addressed to use personally photographed pictuures of the palces you have been or the meal you have eaten, to customize your business card.
The idea is used in minicards they are providing. Business cards with different pictures in the back sides are exciting. He recommand to give the your business card in the begining of your meetings, then they will remember your name during the meeting. In case of minicards, it is better to put them to be picked by each person. This can be good introduction. The picture will help them to remember you.
