The challenge
Small merchants needed to take card payments without buying a terminal, and the operator needed to onboard and monitor thousands of them.
What we built
Two apps: a merchant app with Tap to Pay on iPhone, NFC on Android, QR codes and payouts, and a super-admin app for KYC review, limits and transaction monitoring, backed by a custodial ledger API.
