Big four bank Nedbank says a system error at the end of last week affected consumers trying to shop through Amazon and PayPal.
The bank explains that the system error on Amazon.com and the PayPal online payment portals affected the card CVV authentication process, resulting in the rejection of client transactions.
Head of Nedbank's card risk services, Rene de Villiers, explains that when clients shop online, transactions are validated against the three digits on the signature strip on the back of the card and are then either approved or declined.
However, in the case of Amazon.com and PayPal, the authentication checks did not come back with a CVV number, and as a result Nedbank could not authenticate the transactions, which led to the deals being declined, says De Villiers.
Nedbank did not respond to a query as to how many of its customers were affected, and did not indicate whether the outage affected other Web sites. Neither Amazon nor PayPal were able to revert to queries by this morning.
The error has since been rectified and the system is fully functional. "Nedbank regrets this incident and any inconvenience caused."
