The disruptions began around nine o'clock Thursday morning and meant that some payments could not be processed normally, SVT News reported.
Nets is a provider of payment solutions for various credit and debit cards. The problems affected online and in-store payments and several countries besides Sweden, including Denmark.
Shortly after 2 p.m., the company announced on its website that it was returning to normal operations.
The cause of the disruptions was described as an “internal error”.
