There is a lot of buzz about "business card alternatives". In tech savvy circles many people think it makes them look trendy and cool to loudly announce they do not carry business cards... brazenly proclaiming business cards to be "old school".
I met one young dude who captured the hearts and minds of a group at a networking event with his long song about his being cardless for environmental reasons. He drove an SUV. Poser.
I have encountered a number of people who tell me to to send them a LinkedIn request. Ummmm, why tell me to do all the work. Meeting someone and giving them a homework assignment so they can be connected to you is a bit pompous. Don't ask me to do the work. Lazy.
Worse are those who who profess not to carry cards for any number of reasons, but instruct others to give them a card, promising that they will follow up with an email or social media connection. Silence, no follow up. Liar.
The thing with using technology to replace business cards is that the technology must be pervasive and the user must not drop the ball. Since the odds of these lining up (everyone using the same technology and humans following through later) is zero.... get over yourself and carry business cards.
The reason for having business cards with you is not about YOU, it is about the other person.
Don't be so self-focused that you expect others to operate in the same manner you do when it comes to making connections. I am not damning these technologies, as I use them (I just "bumped" my iPhone with someone a few minutes ago). Technology is great, but to make up reasons to discard business cards thinking you are trendy might make you appear to be a lying lazy poser!
Do not try to prove your coolness to the business community by being a "business card contrarian". I know that our society gets all wacky in love with contrarians... but the truth is we think many of them are jerks at the same time. Prove your coolness by doing great work and helping other people succeed.
Carry cards because it makes it easy for the people you meet to remember you later. You never know who might be the person who could one day bring you an opportunity. Painful to think you are leaving money on the table because people are missing establishing contact because you do not have a business card.
Have A Great Day.
