About Feddi

Feddi gives enterprises a branded, closed-loop wallet that makes payment and loyalty a single action. Customers preload funds and pay with one barcode in the brand’s app/web/WhatsApp; rewards apply automatically or plug into existing programs. Retailers secure prepaid revenue, cut card fees, and capture complete first-party purchase data on every transaction.

(Under the hood for the techies) Feddi Wallet is an SDK + API layer with POS connectors, an event-driven ledger, and a campaign/analytics engine. It’s non-custodial (closed loop; funds stay with the merchant/payment partners) and built for reliability, idempotency, and real-time data.
