Tapping & Meeting

The SONO Card knows five gestures:

1. A first registration — naming the card to your shell
2. A replacement — with a quiet pause, so the old one stays valid for a day
3. A tap by someone else — they arrive on your public shell
4. A frozen card — when you have lost it
5. Your own card — opening its settings

When you tap someone else's card

Your phone learns who they are and lands on their public shell — the door to their MercyChain. From there you can:

• Send a pearl to them
• Request one
• Add them to your circle
• Begin a small written agreement

The meaning of the tap

Two phones can read a QR code and finish each other's sentences digitally. The Card is physical — it asks you to put a thing into another person's hand, and it carries the meaning of that. A meeting, a handover, a goodbye: some moments deserve an object.
