President Obama, a former U of C professor, helped to popularize the fist bump.
Now, two students at the University of Chicago business school developed a company called Bump Technologies. Their iPhone app, called Bump, lets users transfer data from one iPhone (or iPod Touch)to another by bumping them.
You can transfer all your contact info or just some data (like phone numbers).
This shows that there are always simple and elegant opportunities waiting to be capitalized on.
