To order an ID06 card, the cardholders must identify themselves. Identification is most easily done over internet with an eID. Go to https://id06.se/english/ and scroll down to Approved electronic identity services for a list of which eIDs that can be used for verification.
Employees that need ID06 cards, and who do not have an approved eID, can in some cases identify personally with passport or national ID. Go to https://id06.se/english/ and scroll down to Validation of your identity to find which passports and ID documents that are approved for scanning.
Go to sistec.se to find out if your ID or passport can be scanned at this time.
