ZIPSS
Overview
Note on classification. This entry was originally bucketed as a QR standard, but zipss is not a QR-symbol standard — it is a real-time gross-settlement rail. Reclassified as
RTGS. The wiki shows no playground because there is no QR payload to encode; the slug is retained to avoid breaking incoming links.
ZIPSS (Zambia Interbank Payment and Settlement System) is Zambia's real-time gross settlement (RTGS) system, managed + operated by Bank of Zambia (BoZ) in its capacity as settlement provider 1, 2, Zambia report. ZIPSS is an electronic payment system in which processing of transactions for settlement takes place continuously on a transaction-by-transaction basis in real time — designed primarily to improve management of payment risks related to high-value payments while also able to process transactions of any value.
The structural significance: ZIPSS provides final + irrevocable real-time settlement with negligible credit + settlement risk because it's based on pre-funding of payments before payment instruction is issued. Membership open to all banks operating in Zambia with direct connection — comprehensive coverage. Anyone with a bank account at any BoZ-registered commercial bank qualifies to make a transfer through ZIPSS. ZIPSS is the foundational interbank-settlement rail complementing Zambia's mobile-money + retail-payment infrastructure (NFS National Financial Switch, Airtel Money + MTN MoMo Zambia + ZICTA Zambia mobile money operators).
ZIPSS Operating Rules October 2025 illustrate ongoing modernisation. Southern Africa Development Community (SADC) RTGS linkage provides regional cross-border RTGS integration — Zambia connected through SADC RTGS system, joining South Africa, Botswana, Zimbabwe, Mozambique, Tanzania, others.
