Tech: This app is going to kill the business card

  • Knock Knock, a new app, allows you to knock twice on your phone if you want to share your contact information with someone, and once that other person knocks too, the transaction will take place. It automatically remembers the person's profile with their name and photo, as well as the location where you met.
