Quick answer

DebiCheck is an authenticated debit-order scheme launched to give consumers explicit control over debit orders against their bank accounts. The consumer pre-authorises each mandate, the debit is processed via BankservAfrica's DebiCheck PCH, and the net obligation settles in SAMOS at the agreed window.

Why DebiCheck exists

Before DebiCheck, debit orders in South Africa could be set up with relatively weak consumer-side verification, which contributed to dispute and fraud volumes. DebiCheck introduces an authentication step: the consumer confirms the mandate (via their banking app, USSD, or in-branch) before the merchant can debit the account.

How a DebiCheck flow works

  1. The merchant captures the mandate details and sends the authentication request.
  2. The consumer authenticates the mandate via their bank.
  3. For each subsequent collection, the merchant submits a debit instruction matched against the authenticated mandate.
  4. BankservAfrica's DebiCheck PCH clears the debits and computes net positions per participant.
  5. Net positions settle in SAMOS at the scheduled window.

DebiCheck vs older EFT debit

EFT debit orders rely on a paper or electronic mandate held by the merchant. DebiCheck adds a bank-side authenticated mandate, giving the consumer's bank the ability to validate each debit against an authoritative record. The result is fewer disputed debits and stronger consumer protection.

TL;DR

  • DebiCheck = authenticated debit-order scheme.
  • Mandate is authenticated by the consumer via the bank, before collection.
  • Reduces unauthorised-debit disputes.
  • Clears via BankservAfrica DebiCheck PCH; settles in SAMOS.

Frequently asked questions

Is DebiCheck mandatory?

For most authenticated debit orders, yes — it is the standard scheme. Some legacy non-authenticated debit orders still exist under separate rules.

Does DebiCheck stop all debit-order fraud?

No — but it materially reduces unauthorised-debit disputes by adding consumer-side mandate authentication.

Who clears DebiCheck?

BankservAfrica, via the DebiCheck PCH.

How is the net obligation settled?

Through SAMOS, at the scheduled DebiCheck settlement window.
