Become a member

The Association of System Operators (ASO) was created at the beginning of 2007 in preparation for the new structure for participation by non-banks in the formal payment system processes introduced by the South African Reserve Bank (SARB) in conjunction with the issuance of the Directive for Payment System Operators. The ASO is an independent body formed to represent the interests of all Payment System Operators in the RSA. The aim is to provide a non profit forum in which association members can address issues of common interest and interface with payment industry stakeholders, government and regulatory organisations. In this capacity, the ASO will be holding a seat on the South African Reserve Bank (SARB) National Payment System Advisory Board.we like best, every pleasure is to be welcomed and every pain avoided.

But in certain circumstances and owing to the claims of duty or the obligations of business it will frequently occur that pleasures have to be repudiated and annoyances accepted.
