Niyi Ajao, acting managing director of NIBSS explained that NIBSS has been working to enhance capacity in order to take care of the growing volume of transactions since last year, hence the system problem.
Also, implementation of real-time reversal by POS terminals directly. This would require that banks are available to receive such online real-time. This would take effect by or before end of April 2019.
He explained that transaction timeout is the total turn-around-time (TAT) for a POS transaction cycle from the time it is received from a POS to the time a response is sent back to the terminal.
“This TAT had been configured at 15 seconds in agreement with banks and processors. However, delayed responses from Issuers after this timeout in recent times could cause authorised debits not to return to the terminal before the set TAT, hence the adjustment to 45 seconds”.
He said the reversals for failed transactions is one area that NIBSS will henceforth, pay more attention to, so as to strengthen e-payment users confidence in the system.
“Whenever there is a transaction decline the system is supposed to reverse the transaction such that a debited cardholder would receive a reversal credit. Delays on reversal could be caused by platform downtime, network issues at processor level or delayed responses and Issuer/Switch Inoperative – Processor or bank is not available to receive the reversal even when it’s transmitted by NIBSS,” Ajao said
