Important information for those using Croatian highways as toll booths are currently not accepting payment by card.
Owing to the current technical collapse in the usual system, HAC-ONC toll booths aren't accepting card payments, therefore, drivers who planned to pay the toll charge by card will need to find a place to get some cash (pretty difficult if you're already in the middle of the road).
Zagrebacka Banka claims they are aware of the problem in the system and are actively working on resolving the issue.
