Card payments booked twice after SIX suffers IT glitch in Alps

SIX Payment Services has apologised to its customers in Switzerland and Liechtenstein after a technical problem caused debit card transactions in the Alpine countries to be booked twice. 

The card payment processing problem occurred on 22-23 January and resulted in transactions being booked on both nights during the overnight batch process procedure, rather than just the once.

SIX Payment Services, which processes 1.4 million transactions on Swiss and Liechtenstein debit cards every day, insist that the vast majority of erroneous payments were not executed and that 99.93% of the double bookings were reversed quickly, with the remaining transactions being unwound this week and reflected in bank accounts.

No customers have lost money as a result of the IT problem but it is an embarrassment for the industry following on from earlier computer problems at Lloyds Banking Group in the UK when a server failure crashed its cash machines and debit card payment operations. RBS has also notoriously suffered numerous IT failures recently in its core banking and payment systems and the issue of aging, old siloed infrastructures’ failing resiliency is likely to be a hot topic throughout 2014.
