## 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** <sup>[1][1], [2][2], [Zambia report](https://docs.barcoder.ai/docs/payments/ZM)</sup>. 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](https://docs.barcoder.ai/docs/standards/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.
