That's very interesting, not least because Särö is about 5 km from me

The postcode 43040 no longer exists but the range of postcodes used in Särö is still in that ballpark (429xx).
Automation means the same in Swedish as in English - it is the act or process of making something automatic. Automater is the plural form of automat, the actual machine involved. Whether Pan Nordic Automater and Pan Nordic Automation are the same entity I don't know; Särö certainly strikes me as a strange place to have a large industrial concern, since it consists mainly of large detached houses and not commercial areas. But the financial HQ of an organisation need not be the same place as where its products are made or stored, of course.
I will see if I can dig further at Bolagsverket (equivalent of Companies House), since if the Särö organisation is the same as the token issuer, I need to add it to the material for the Halland tokens book we're working on at Gothenburg Numismatic Association.
