How offline QR works
Merchant generates QR
The merchant app generates a signed QR code for the transaction — no internet required. The QR contains an encrypted payment token.
Customer scans
The customer scans with their AfriLink app. The payment is authorised locally using a cached credential — no network call needed.
Both apps confirm
Both apps show a local confirmation. The transaction is cryptographically locked — it cannot be replayed or altered.
Sync when online
When connectivity returns, both devices sync. The transaction settles to the merchant's account within 3 seconds of reconnection.
Built for where Africa actually pays
📡 Offline-first architecture
The AfriLink merchant app is built as an offline-first PWA. All payment logic runs on-device — the network is for settlement, not for transaction approval.
🔐 Signed transactions prevent fraud
Every offline QR token is cryptographically signed with a device key. Tokens expire, cannot be replayed, and are invalidated at settlement. Zero offline fraud in testing.
📉 Works on 2G
The sync payload is under 2KB. Even on the weakest 2G signal — GPRS, EDGE — transactions settle in seconds. No 4G/LTE required.
📱 Tiny app footprint
The offline-capable merchant app installs in under 50KB. Designed for entry-level Android devices with limited storage — because that's the real device landscape.
🔄 Sync on reconnect
Transactions queue locally with full integrity. The moment a Wi-Fi or mobile signal appears, the queue drains automatically — merchant and customer balances update together.
🏪 Merchant + customer apps
Both sides of the payment run offline-capable AfriLink apps. Markets, hawkers, kiosks, delivery riders — the full offline QR ecosystem works end-to-end.
Where offline QR transforms commerce
Open-air trading
Traders in Makola, Balogun, and Onitsha market accept digital payment — no data plan required mid-day.
Farmgate collection
Pay farmers in remote areas without mobile coverage. Transactions settle when the collector's vehicle returns to signal range.
Trotro & bus fares
Conductors collect fares digitally — even on rural routes with no coverage. Sync happens at the terminus.
Outdoor festivals
Vendor payments at congested events where mobile networks are saturated — offline QR keeps the queue moving.
