Bus Vannin has reported a spike in declined bank card transactions in the last few hours, prompting a warning to passengers across both bus and rail services.
The operator says it is working with its team and suppliers to identify the cause, but cautions that the issue may not be resolved until after the weekend.
Customers are being strongly advised to use prepaid smart Go Cards or cash to avoid disruption to travel.
Bus Vannin apologised for any inconvenience caused.
