What “real-time payments” means in South Africa
In South Africa, real-time payments are electronic fund transfers that move money between bank accounts almost instantly, with funds clearing in seconds, 24/7. This system, primarily driven by the PayShap rail, is a direct alternative to traditional methods that can take days to settle. The scope is broad, aiming to displace cash for everyday transactions and improve financial inclusion. However, adoption has been gradual; despite the country being an early mover in this space, real-time transactions accounted for only 1.7% of payment volume in 2023. No formal legal statute defines the term; it is operationally defined within the national payments framework.
The South African Reserve Bank (SARB) acts as the lead regulator, guiding the modernization of the country's payment ecosystem. The primary operator of the PayShap rail is BankservAfrica, which developed the system in partnership with the Payments and Banking Associations of South Africa. BankservAfrica is the main automated clearing house involved. While the specific messaging protocol for PayShap is not detailed, new real-time systems globally are built on the ISO 20022 standard for its rich data capabilities and interoperability, making it the likely framework (industry norm).
South Africa was an early pioneer of real-time payments but has since fallen behind global leaders in adoption, a gap the modern PayShap system is now intended to close.
Payment Rail Overview
Real-Time Clearing (RTC)
Introduced in 2006, Real-Time Clearing (RTC) was South Africa's first foray into instant interbank payments. The system facilitates real-time fund transfers directly between participating banks. Despite its long-standing presence, its impact has been muted due to high bank fees, limited participation, and low public awareness.
- Interbank Instant Payments: The system's core function is to clear payments between different banks in real time.
- Legacy System: As one of the earlier real-time systems globally, it established the initial infrastructure for instant payments in the country.
Pros and Cons
- Pro: Pioneered instant payment capabilities in South Africa, establishing an early foundation.
- Con: Suffers from high transaction fees and low adoption, resulting in minimal market share.
PayShap
Launched in March 2023, PayShap is a modern, mobile-centric payment rail designed to make instant payments accessible and affordable. It allows users to send money 24/7 using a simple identifier like a mobile number (ShapID), bypassing the need for traditional bank account details. The system is a key part of South Africa’s payment modernization strategy, aiming to accelerate the shift away from cash.
- Proxy Payments: Users can transact using a "ShapID," typically a mobile number, which increases security and convenience by masking bank account information.
- Request-to-Pay: This feature allows businesses and individuals to send a payment request, which the recipient can approve with a single tap in their banking app for immediate settlement.
- Constant Availability: Unlike traditional bank transfers, PayShap operates around the clock, including on weekends and public holidays.
- Financial Inclusion Focus: The system is built to serve underbanked populations and informal markets by offering a low-cost digital alternative to cash.
Pros and Cons
- Pro: Offers a simple, low-cost, and mobile-friendly experience for instant payments.
- Con: Adoption has been slow, hampered by a lack of promotion from banks and low public awareness since its launch.
- Con: Transactions are final and cannot be reversed, which can complicate dispute resolution.
Limits, Fees, and SLAs
- Limits: PayShap transaction limits are set by banks, with many supporting single payments up to R50,000. Daily caps and distinct corporate tiers are not specified.
- R2P Fees: Fees are set by individual banks and are generally low for smaller transaction values. Users should check their bank’s specific tariff guide.
- Operating Hours: The PayShap system operates 24/7/365, including on weekends and public holidays, with no specified cut-off times for processing transactions.
- Failures & Returns: PayShap transactions are final and cannot be reversed. For incorrect payments, users must contact their bank to log a dispute, but resolution is not guaranteed.
Compliance and Risk
KYC/KYB & AML
South Africa’s regulatory framework, primarily the Financial Intelligence Centre Act (FICA), mandates that all financial institutions perform rigorous Know Your Customer (KYC) and Anti-Money Laundering (AML) checks. This includes customer identification, ongoing transaction monitoring, and reporting suspicious activities to the Financial Intelligence Centre.
Data Residency & Privacy
While specific data residency mandates are not explicitly detailed for payment systems, financial institutions operate under a broad requirement for data security. This falls under the SARB’s oversight of the national payment system and general data protection principles within compliance programs.
Fraud Controls
Regulatory oversight for fraud is managed by the SARB, which promotes initiatives like DebiCheck to combat payment fraud. Financial institutions are responsible for implementing their own security measures and reporting suspicious transactions, forming a layered defense against illicit activity.
Recordkeeping & Audits
Under the Financial Intelligence Centre Act (FICA), all accountable institutions must maintain comprehensive records of customer identities and transaction histories. This creates a clear audit trail, allowing regulators to verify compliance and investigate financial activities when necessary.
Lightning Network Integration as a Solution
The Lightning Network is a second-layer protocol on Bitcoin that processes transactions off-chain for near-instant, low-cost payments. While domestic RTP rails offer real-time settlement within a country, they are often confined by geography. The Lightning Network complements these systems by providing a global, interoperable infrastructure for international payments, filling a critical gap where local systems cannot operate.
While both systems offer near-instant settlement, the Lightning Network provides a significant cost advantage, with fees often a fraction of a cent, making micropayments viable. Domestic rails are confined to a single country's banking system. In contrast, the Lightning Network operates on a global scale, connecting users across borders without intermediaries and offering financial access to anyone with an internet connection.
- Cross-border complexity: It bypasses traditional banking intermediaries, removing high fees and currency conversion delays for international payments.
- High transaction fees: By moving payments off-chain, it dramatically reduces costs, making small or frequent transactions economically practical.
- Scalability limitations: The network can process millions of transactions per second, overcoming the throughput constraints inherent in many foundational blockchain protocols.
Exploring the Lightning Network offers a view into a future of truly global, open, and instantaneous value transfer.

Cross-Border Transactions and Remittances to South Africa
Cross-border RTP is challenging due to fragmented systems and regulatory friction. Reaching South Africa involves navigating complex FX paths and stringent compliance checks that slow transactions. While multi-rail propositions and rail bridging solutions aim to connect disparate payment networks, the process remains difficult. Security is a primary concern for senders, with 46% of South Africans ranking it as their top priority, adding another layer of operational difficulty for payment providers.
- South Africa – Zimbabwe: Remittances are a critical lifeline, with funds often sent to support family members. These payments are essential for daily survival, a reality for many recipients who depend on this financial support.
- South Africa – United Kingdom: This corridor sees a mix of personal remittances and business-to-business payments. Transactions support everything from family expenses to payments for tourism services, reflecting deep economic and personal ties.
- South Africa – Nigeria: As two of Africa's largest economies, this corridor is dominated by B2B transactions for trade and services. The Pan-African Payment and Settlement System (PAPSS) is designed to simplify these transfers by allowing settlement in local currencies.
The Lightning Network directly addresses these cross-border issues by operating on a global, open protocol. It bypasses traditional intermediaries, facilitating real-time settlement and reducing transaction costs to a fraction of a cent, making international payments both instant and affordable.
