The end of the buissnus card

Well this might be a useless blog but i thought id get this theroy of my mind, well probarly not mine but i thought id write a blog on it. I deal with a lot of people in the music industry from managers, Producers, A&R. I meet new people all the time and something ive descoverd not only from myself but from others, people dont give buissnus cards out anymore , they just put a number on there phone or, in there way of making a postive contact, which takes a bit more time than just giving a card out. But i think its easier to do that than just giving a card out that someone might just lose, but there is a 80 percent chance they wont lose it on there phone. I must admit i have started doing that myself than giving a card out. Its now the era of the Digital buissnus card of just simply sending it through your bluetooth device.
