Quick answer
SAMOS is the wholesale RTGS system operated by SARB for high-value interbank payments; PayShap is the consumer-facing instant-payment scheme operated by BankservAfrica for low-value transfers between bank accounts in seconds. Different operators, different user base, different value tiers — but PayShap still ultimately settles in SAMOS at frequent windows.
Who runs each
SAMOS: South African Reserve Bank, on its own infrastructure. PayShap: BankservAfrica, with industry oversight via PASA.
Who actually uses each
SAMOS is used by banks themselves and by corporate treasury teams for high-value, urgent transfers. PayShap is used by retail consumers and small businesses for everyday peer-to-peer payments via a phone number, email address, or proxy ID.
Speed comparison
Both settle quickly from the user's point of view. A SAMOS RTGS payment typically completes in seconds once liquidity is available. A PayShap payment also completes in seconds end-to-end, but the underlying interbank settlement runs at scheduled windows in SAMOS that occur frequently enough — including over weekends — to support that customer experience.
Typical amounts
SAMOS: tens of thousands to hundreds of millions of rand per transaction. PayShap: retail amounts, typically a few thousand rand per payment, with scheme-level limits.
Side-by-side comparison
| Attribute | SAMOS | PayShap |
|---|---|---|
| Operator | SARB | BankservAfrica |
| Users | Banks, corporate treasuries | Retail consumers, SMEs |

How they relate
PayShap is not a replacement for SAMOS. PayShap depends on SAMOS for final settlement — every PayShap net position eventually flows through a SAMOS settlement window. SAMOS is the foundation; PayShap is the consumer-friendly product on top.
TL;DR
- SAMOS = wholesale RTGS; PayShap = retail instant-payment scheme.
- Different operators (SARB vs BankservAfrica) and different users.
- PayShap settles into SAMOS at frequent windows.
- They complement each other, not compete.
