Nigerian Certified Aggregation Switch DML

A Nigerian Certified Aggregation Switch, also known as a Payment Terminal Service Aggregator (PTSA), is a CBN-licensed platform that ensures interoperability, standardization, and secure routing of all PoS transactions across Nigeria.

Overview

A Certified Aggregation Switch in Nigeria functions as a central hub that aggregates and routes transactions from all Point of Sale (PoS) terminals deployed by banks and licensed card schemes. These switches are certified and licensed by the Central Bank of Nigeria (CBN) to ensure compliance with technical and operational standards, enabling interoperability, uniform functionality, and next-day settlement of PoS transactions .

Key Functions

• Interoperability and Aggregation: The switch connects all PoS terminals in Nigeria, allowing them to accept cards from any bank or licensed card scheme without discrimination .
• Terminal Certification: Ensures that all PoS devices meet technical and operational standards, guaranteeing constant availability and uniform functionality .
• Transaction Routing: All PoS transactions at merchant and agent locations must be routed through a CBN-licensed PTSA, which then forwards transactions to processors certified by the relevant payment scheme .
• Value Added Services (VAS): Certified switches can enable additional services on PoS terminals, such as loyalty programs, bill payments, and other digital services .

Licensed Aggregators in Nigeria

• Nigeria Inter-Bank Settlement System Plc (NIBSS): The first PTSA licensed by the CBN in August 2011, serving as the primary aggregation switch for PoS transactions .
• Unified Payment Services Limited (UPSL): Licensed in April 2024 to diversify the aggregation ecosystem and reduce reliance on a single aggregator .

Compliance and Regulatory Requirements

• All Payment Service Providers (PSPs) must route PoS transactions through a certified aggregation switch .
• PoS agents are required to register their businesses with the Corporate Affairs Commission (CAC) to operate legally .
• Aggregators must ensure that transactions are sent only to processors certified by the relevant payment scheme and licensed by the CBN .

Importance

Certified aggregation switches are critical for monitoring electronic transactions, preventing fraud, and enhancing the efficiency and reliability of Nigeria's payment system. They also support the ubiquity of digital payments, ensuring that all PoS terminals function seamlessly across the country . In summary, a Nigerian Certified Aggregation Switch (DML) is a CBN-approved platform that centralizes PoS transaction processing, enforces technical standards, and enables interoperability across all banks and licensed card schemes, with NIBSS and UPSL being the primary licensed operators .
