Most people in the tech industry have an iPhone and they have updated it to IOS6. So, why are people still giving out card?. I just email or text my URL and wholla they have my card. Best part is now I have a way to update my circle on whats going on with me. Say, I have an event, I just update my PassCard and they are notified.
If you have not figured it out by now, I am one of the developers of PassHound and I see the potential of PassBook even if it is self serving at the moment. So, if you want to keep up on what I am doing or just want my contact information, well here it is.
