Do You Poken?

Set to revolutionize the way social-networkers socialize. This keyring-friendly USB device lets you swap contact details instantly. Simply pull out your Poken and ‘high five’ it with your new best friend’s. Clever RF technology then zaps the info between the devices,
so next time you log on to your favorite site, your profiles are linked.

Cons: Needs a slicker, cleaner and fresher user-interface.

ps: there are apps for the i-phone w/ the same tech. ;)
