Participant — overview

The participant is the only profile without a password: phone + SMS code (OTP) login. There's no separate sign-up — the same flow handles both the first visit and a returning one.

What the participant can do today​

  • Log in/out/refresh by phone (OTP).
  • View and edit their own global profile.
  • Find an event by a short code and activate their own wallet in it.
  • Check their own wallet's balance for an event.
  • List every wallet they already have, across every event.
  • Pay at a PDV via QR or NFC — read the payload the PDV generated, see the amount, and confirm the payment from their own app, no PIN (login is already the factor).

What doesn't exist yet: topping up their own wallet directly — top-up today only happens cashier-assisted (see Cashier), the participant can't top up on their own —, transaction history.

Where everything lives​

One wallet per event, never shared​

A participant can have several wallets — one per event they took part in — but never two wallets in the same event. Each wallet has completely isolated balance, currency, and history from the others; there's no "global balance" adding everything up across events.
