When you meet with somebody new you exchange your online credentials by nearing your Pokens. If the data has been transferred the Poken hand will glow green. If faulty the hand will glow red.

Up to 64 contacts can be stored on the Poken. If you don’t upload the data to the website on the Internet, the oldest contact will be erased from the memory when adding on a next contact. Price is about €15 or $20 and to be purchased online of course. The company Poken SA is from Lausanne in Switzerland and has a presence on Facebook.

Already popular in schools, not yet in use for business: but that can change soon. If teenagers can use it, their parents will be able too: they just need to ask their kids.
