Adopting a Japanese networking tradition; business cards. They always have one (probably several) available, for every occation and situation. It doesn`t matter if the only word uttered is hi. You`re still on the vip list worthy a card. Which I guess is a very nice thing. Only problem: to remember the people behind every hi. My solution: personal cues added to the excisting information. E.g. Tomi Ogata, photomaker, Tokyo + extremely skinny pink jeans, plastic hat, favourite color: yellow.
(the card is not supposed to have the dotted line and half a scissors, it is just to make a frame on this white background)(just so you know)
