The bracelet shows the number of people the users have in common. The number of beads lighting up are the number of people the users have in common. When shaking hands, the bracelets exchange information, and add each other to the list of people. All the beads can light in two colors, blue and pink. The different colors of the beads gives a clue to your relationship with the persons. Blue means that you know the person from work, and pink means you know the person from your sparetime. The beads don´t give any clue to who the persons really are, that is up to the users to find out.

Scenario
You shake hand with another bracelet user on a party, and two beads on the corresponding bracelets light up. From left to right your beads are blue and pink. From the other user the beads show the colors pink and pink. That means that the first person you have in common you know from work, but the other user knows him or her from sparetime. The next bead shows the color pink, so that is someone you both know from your sparetime. Now you just have to figure out who the persons are, and that makes a good start for a conversation.
