Business cards are so old-school.
The new way to exhange information? The poken, an electronic portal for personal deets. Basically, it works like this:
2. Touch your poken to someone else's.
3. Upload that person's information to your computer, and they can do the same.
I got the gadget at a recent social media gathering, and it's pretty nifty—even if it must reach critical mass to prove useful.
