Polling staff always work in pairs. The other polling staff member scans your ID or enters your personal identity number in order to find your electoral roll number.
For various reasons, for example due to technical issues or if you are a Swedish citizen living abroad and are no longer on the electoral register, a polling staff member may need to receive your vote outside the digital voter list.
In that case, the polling staff member will record your details by hand on a paper voter list.
The authority will then link your vote to the digital voter list so that it is sorted together with the other early votes.
