Swish payment services experienced technical problems overnight. The disruption affected transactions to and from SEB bank customers.
Swish announced the issue on its official website. The company confirmed the problem began during the overnight hours.
Just after 2:30 AM, Swish reported resolving the technical issues. The timing coincided with the daylight saving time change.
Several Swedish banks conducted maintenance work simultaneously. Skandiabanken, Sparbanken Syd, and Nordea all performed system updates.
These maintenance activities could also impact payment services. The banks scheduled completion times between 3:30 AM and 4:00 AM.
Swish dominates Sweden's mobile payment market. Nearly 8 million Swedes use the service regularly.
The simultaneous timing of multiple bank maintenance windows raises questions about coordination. Such overlapping disruptions create broader system vulnerabilities than necessary.
Technical glitches remain relatively rare for Sweden's payment infrastructure. The country leads Europe in cashless transaction adoption.
