Visa’s credit card processing system was once again working around 5 p.m. Monday after it crashed earlier in the afternoon, leaving Canadians to reach for their billfolds.

“Visa is 100 per cent operable. The Visa network is working,” a Visa spokesperson said. “The issue is with a third party provider.”

A spokesperson for TSYS, the company that provides Visa’s payment authorization system said via email that a power disruption at a TSYS data centre was responsible for the service outage.

Royal Bank of Canada, TD Canada Trust and CIBC said their customers were among those affected by the nationwide outage.
