Invite Link & QR Sharing

HLF explicitly identified recruitment as a strategic priority, framing the mobile app itself as a marketed membership benefit and a vehicle for peer-mentor-driven member growth. By embedding invite-link and QR-sharing directly in the app, the platform lowers the barrier for peer mentors to recruit contacts they interact with daily, turning organic in-person interactions into tracked referral events. This reduces the organization's reliance on centralized marketing campaigns and leverages the trust inherent in peer-mentor relationships. The QR code format is particularly relevant for in-person events and workshops where digital sharing is impractical, broadening reach beyond digitally fluent audiences.

Invite links should be short, unique URLs that encode a referral token tied to the generating peer mentor's user ID. The backend generates and persists the token; the mobile app fetches it on demand and hands it to the platform's native share sheet via Flutter's share_plus package. QR code rendering uses a client-side library (e.g. qr_flutter) so no server round-trip is needed for display. Deep-link handling on the registration flow must extract and validate the referral token and associate the new account with the referrer before token expiry. Token expiry, revocation, and reuse limits should be configurable per organization in admin settings. WCAG 2.2 AA requires that the QR code is supplemented with a copyable text link as a non-visual alternative.
