The National Payments System (NPS) consists of all systems which facilitate the clearance and settlement of payments. These comprise the systemically important Real Time Gross Settlement (RTGS) system also referred to as Safe-tt, which facilitates large value and time critical payments and Significant Retail Payment Systems.
These SRPS include the Automated Clearing House/Electronic Funds Transfer System (ACH/EFT) for batch processing of reoccurring payments such as salaries and utilities, the Automated Clearing House/Electronic Cheque Clearings system (ECCS) and the Debit Card Switch system (LINX).
