It is currently not possible to pay by card at ST1's and Shell's petrol stations, reports Aftonbladet.
The problems have been ongoing throughout Sunday and affect all stations in the country.
At present, there is no prognosis for when the fault can be rectified.
Work is being done from all angles to get as much up and running as possible, says Faisal Ouahid, press spokesperson at ST1, to Aftonbladet.
