POS Transaction: Point of Sale transactions on Paga allows individuals using their ATM cards access to cash via an agent on Paga.
How it Works.
Customer/individual wishes to withdraw cash from the Agent. The customer inserts his/her ATM card into the agent’s POS device and enters his/her pin. PTSP kickoff requests to generate transaction reference from the Bank. The Switch operators (ISW/NIBSS) relay response to generate transaction reference from the Settlement bank. Once the response received is positive, the PTSP Initiates payment API call with requested parameters to the Switch operator.
Interswitch/NIBSS splits the transactions into the agreed sharing, engage source and Paga Settlement banks with a request. Paga sends a response to credit the request to the switch operator. The Switch operator relays the Source bank response to the Settlement bank and sends a print receipt pulse to the POS. The Cardholder’s account is then debited with the transaction value. The Switch operator again relays the Source bank response to the Settlement bank and sends a print receipt pulse to POS.
The agent’s account is credited with the value of the transaction by Paga and also the commission earned. The agent gives cash to customer
PTSP: This means Payment Terminal Service Provider. They are responsible for the deployment, maintenance and support of payment terminals on behalf of the acquiring bank.
Switch Operators: These are intermediaries and processors mediating between the source (Initiator) and the beneficiary. E.g NIBSS- Nigeria Inter-Bank Settlement System, ISW- Interswitch.
Points of Possible Failure (POF) for POS Transactions.
Points of failures are scenarios that truncate the smooth operationalisation of the transaction. These are issues that may lead to situations where the Paga user/recipient is not credited with the value of the transaction. Below are points of failure for POSTransactions:
A. The transaction may fail between the PTSP and the Processor: Due to network failure, the PTSP may be unable to communicate with the processor.
B. The transaction may fail between the Processor and the Bank: The switch operator may not receive a response after sending a signal to the bank.
C. The transaction may fail between the PTSP and Paga Platform: The PTSP after receiving a response from the processor then communicates with Paga. As a result of a technical glitch, this flow may be truncated.
D. The transaction may fail between Paga Platform and the Receiver’s account (Agent): The transaction value may not be credited to the agent’s Paga account after a successful transaction.
